Abstract: A quick release restraint device for such uses as restraining prisoners being transported in police vehicles, which includes a mechanism to quickly release the restraint device in the event it is necessary to rapidly move the restrained prisoner out of the vehicle in the case of an accident or other emergency wherein his life or safety may be endangered. The restraint comprises a strap member having a buckle at one end to secure to the handcuffs of the prisoner, and a releasable loop at the other end to secure to an anchoring member of some kind permanently affixed to the vehicle. The releasable loop is doubled back, with the doubled back portion received and held in an elongated sleeve which surrounds a portion of the strap. The releasable loop is held in place as long as the doubled back portion is within the elongated sleeve, but it may be rapidly undone to release the prisoner by pulling the doubled back portion out of the sleeve by a hand grasp member which projects outwardly of the sleeve.
