Abstract: A hand restraint device for restraining the hands of an individual and preventing them from using their fingers and thumbs is disclosed. The hand restraint device comprises a pair of mitts for connection to a pair of standard handcuffs. The mitts comprise pockets of material with a closed end and open end for enveloping the hands of the wearer. Each mitt includes a durable hand enclosure and elastic wristband. The handcuffs encircle the wearer's wrists, passing through a ring connected to the outside of the wristband of each mitt. A rib is located at the open end of each mitt on the outside of each wristband, preventing the wearer from sliding the mitts from underneath the handcuffs.
