A handcuff cover is a plastic or metal cover that can be placed over a pair of handcuffs. It consists of a hinged, box-like assembly locked over the handcuff chain, wristlets and keyholes.[1]

The first handcuff cover was invented by J. D. Cullip and K. E. Stefansen[2] and patented in 1973.[3] It is made from high-strength, high-impact ABS plastic[4] and is still distributed by C & S Security Inc. as "Black Box" handcuff cover.[5] Other companies sell similar devices, e.g. CTS Thompson ("Blue Box" handcuff cover) or Sisco restraints.

A handcuff cover has two key purposes:[6]

  • It converts a pair of standard chain link handcuffs into rigid handcuffs, providing a rather more severe restraint.
  • It covers the keyholes of the handcuffs for further security.

In most cases, a handcuff cover is used in combination with a martin link belly chain which fixes the handcuffs at waist level. This provides a rather uncomfortable restraint and may result in injury to the individual if maintained for an extended period of time.[7] When using a handcuff cover in combination with a belly chain, the hands may be cuffed in a parallel or in a stacked position.

front stack position

In the stacked position, the shackled person's freedom of movement is strongly restricted and the arms are kept in a rather unnatural position which may cause discomfort or even pain[8] because in this arrangement, the individual's wrists are restrained in close proximity to the torso.[7]

parallel position

In a parallel position, the restraint will cause the wrists to spread outwardly in an angular relationship.[7] As the handcuff cover provides a rigid structure, the individual's wrists may be bruised or cocked, restricting blood circulation.[7] However, some models come with angled ends which allows hands and arms to relax in an appropriate posture, therefore reducing physical stress on the individual being transported.[9]

A handcuff cover can also be linked with a connector chain to a pair of leg irons. Individuals with a handcuff cover fitted over their handcuffs can also be restrained together for transportation using so-called "gang chains".[10]
