Encyclopedia > Handcuffs

Handcuffs are restraint devices designed to secure an individual's wrists close together. They comprise two halves, linked together by a chain, hinge or in the case of rigged cuffs - a bar. Each half has a rotating part which engages with a ratchet which is closed around a person's wrist. Without the key, the person cannot move their wrists more than a few centimetres (inches) apart, making many tasks difficult or impossible. This is usually done to prevent suspected criminals from escaping police custody. For the municipality in Germany, see Wrist, Germany. ... Look up chain in Wiktionary, the free dictionary. ...

There are two distinct subtypes of contemporary metal handcuffs: one in which the cuffs are held together by a short chain, and another, of more recent origin, which uses a hinge for this purpose. Since the hinged handcuffs are somewhat smaller when fully extended they are seen as being more easily utilized by a police officer who has relatively small hands, and are also regarded by some observers as more secure because the wrists end up being held closer together than with the chain subtype, and are also bound more rigidly. A third type, the rigid handcuff, has a metal block or bar between the cuffs. Whilst bulkier to carry it permits several variations in cuffing and, with one hand cuffed, can be used in control and restraint techniques. Various accessories are available to improve the security or increase the rigidity of handcuffs, including boxes that fit over the chain or hinge and can themselves be locked with a padlock.

Sometimes two pairs of handcuffs are needed to restrain a person with an exceptionally large waistline because the hands cannot be brought close enough together; in this case, one cuff on one pair of handcuffs is handcuffed to one of the cuffs on the other pair, and then the remaining open handcuff on each pair is applied to the person's wrists. Oversized handcuffs are available from a number of manufacturers, as are juvenile-sized restraints, though none of the latter in current production are approved for use by the United States National Institute of Justice. The National Institute of Justice (NIJ) is the research, development and evaluation agency of the United States Department of Justice. ...

Double locks

Handcuffs with double locks have a lock-spring which when engaged, usually using the top of the key, stops the cuff from ratcheting tighter to prevent the subject from tightening them. Tightening could be intentional or by struggling, when tightened the handcuffs may cause nerve damage or loss of circulation. Double locks also make picking the locks more difficult.


Main article: PlastiCuffs

Plastic restraints, known as wrist ties, plasticuffs, flexicuffs, flex-cuffs, tri-fold cuffs, or zip-strips, are lightweight, disposable plastic strips resembling electrical cable ties. They can be carried in large quantities by soldiers and police and are therefore well-suited for situations where many may be needed, such as during large-scale protests and riots. In recent years, airlines began to carry plastic handcuffs as a way to restrain disruptive passengers. Disposable restraints are considered by many[who?] to be highly cost-inefficient; they cannot be loosened, and must be cut off to permit a restrained subject to be fingerprinted, or to attend to bodily functions. It is not unheard of for a single subject to receive five or more sets of disposable restraints in their first few hours in custody. Recent products have been introduced that serve to address this concern, including disposable plastic restraints that can be opened or loosened with a key; more expensive than conventional plastic restraints, they can only be used a very limited number of times, and are not as strong as conventional disposable restraints, let alone modern metal handcuffs. In addition, plastic restraints are believed by many[who?] to be more likely to inflict nerve or soft-tissue damage to the wearer than metal handcuffs.[citation needed] A demonstrator is cuffed with plasticuffs. ...

Leg irons

On occasions when a suspect exhibits extremely aggressive behavior, leg irons may be used as well; sometimes the chain connecting the leg irons to one another is looped around the chain of the handcuffs, and then the leg irons are applied, resulting in the person being "hog-tied". In a few rare cases, hog-tied persons lying on their stomachs have died from positional asphyxia, making the practice highly controversial, and leading to its being severely restricted, or even completely banned, in many localities.

Most modern handcuffs in Canada, the United States, the United Kingdom and Latin America can be opened with the same standard universal handcuff key. This allows for easier transport of prisoners and keeps one out of trouble if one loses one's keys. However, there are handcuff makers who use keys based on different standards. Maximum security handcuffs require special keys. Handcuff keys usually do not work with thumbcuffs. Recently, a number of padlocks have been marketed which use this same standard key. Latin America consists of the countries of South America and some of North America (including Central America and some the islands of the Caribbean) whose inhabitants mostly speak Romance languages, although Native American languages are also spoken. ...

Old handcuffs

In the past, police officers typically handcuffed arrested persons with their hands in front of them, but since approximately the mid-1960s behind-the-back handcuffing has been the standard. The vast majority of police academies in the United States today also teach their recruits to apply handcuffs so that the palms of the suspect's hands face outward after the handcuffs are applied; the Jacksonville, Florida Police Department and the Los Angeles County Sheriff's Department are notable exceptions, as they favor palms-together handcuffing. In addition, suspects are handcuffed with the keyholes facing up (away from the hands) to make it difficult to open them even with a key or improvised pick.

Escaping from handcuffs is a common stunt performed by magicians, perhaps most famously Harry Houdini. “Illusionist” redirects here. ... Houdini redirects here. ...

There are ways of escaping from handcuffs:

  1. slipping your hands out
  2. lock picking
  3. releasing the pawl with a shim
  4. or simply opening the handcuffs with a duplicate key, often hidden on the body of the performer before the performance.

The above methods are often used in escapology. As most people's hands are larger than their wrists, the first method was much easier before the invention of modern ratchet cuffs, which can be adjusted to a variety of sizes. Modern handcuffs are generally ratcheted until they are too tight to be slipped off the hands. However, slipping out of ratchet cuffs is still possible. During his shows, Harry Houdini was frequently secured with multiple pairs of handcuffs. Any pair that was too difficult to be picked was placed on his upper arms. Being very muscular, his upper arms were far larger than his hands. Once he had picked the locks on the lower pairs of handcuffs, the upper pair could simply be slipped off.

It is also technically possible to break free[1] from handcuffs by applying massive amounts of force from one's arms to cause the device to split open or loosen enough to squeeze one's hands through, however this takes exceptional strength (especially with handcuffs made of steel). This also puts an immense amount of pressure on the biceps and triceps muscles, and when tried by suspects (even unsuccessfully) can lead to injury, including bruising around the wrists, or tearing the muscles used (including dislocating them from the bone itself). For other uses, see Steel (disambiguation). ... Look up Biceps in Wiktionary, the free dictionary. ... The triceps brachii muscle is a large three-headed skeletal muscle found in humans. ...

Another common method of escaping (or attempting to escape) from being handcuffed behind the back, is that one would, from a sitting or lying position, bring one's legs up as high upon one's torso as possible, then push one's arms down to bring the handcuffs below one's feet, finally pulling the handcuffs up using one's arms to the front of one's body. This can lead to awkward or painful positions depending on how the handcuffs were applied, and typically requires a good amount of flexibility. It can also be done from a standing position, where, with some degree of effort, the handcuffed hands are slid around the hips and down the buttocks to the feet; then sliding each foot up and over the cuffs. These maneuvers, and the reverse (otherwise impossible) maneuver of bringing the handcuffed hands up behind the back and forwards over the head and then down in front, can be done fairly easily by some people who were born without collarbones because of the inherited deformity called cleidocranial dysostosis.

From this position, one has a better chance of attempting to use a tool (such as a shim or lockpick) to work one's way out of the handcuffs. Lock picking is the art of unlocking a lock without its intended key. ...


In Japan, if someone is photographed or filmed while handcuffed, their hands have to be pixelated if it is used on TV or in the newspapers. This is because someone who had been arrested brought a successful case to court arguing that being pictured in handcuffs implied guilt, and had prejudiced the trial. Similarly, in Hong Kong, people being arrested and led away in handcuffs are usually given the chance by the policemen to have their heads covered by a black cloth bag. There are holes on the bag for the suspect to see through.[citation needed] For other uses, see Photograph (disambiguation). ... This article is about the graphical editing/censorship technique. ...

Police handcuffs are sometimes used in sexual bondage and BDSM activities. This is potentially unsafe, because they were not designed for this purpose, and their use can result in nerve or other tissue damage; bondage cuffs were designed specifically for this application.

Metaphorical uses

Handcuffs are familiar enough for the word to be used in metaphors, e.g.:

  • Golden handcuffs – an incentive given to an employee by a firm, most or all of which must be repaid to the company if the employee leaves the firm within a specified period of time.
  • As a verb, meaning to be kept from doing something by another's (in)action – "He said that his computer work is handcuffed by his internet provider's refusal to accept .zip files."
