Abstract
A clamp that may be attached to a vehicle door to hold the door closed without damaging the vehicle is described. The device may be used by a police officer to secure the door of the vehicle, thereby preventing the occupants from opening the door suddenly and injuring the officer or fleeing. The mechanism for closing the clamp may be powered by a number of means, including an electrical motor, a hand pull, a spring, compressed air, and the like. The device includes a means for releasing the clamp when the officer no longer has reason to suspect that the occupants will injure him or flee.
