ABSTRACT:
A device for securing the tailgate of a pickup truck, so that it can not be removed by unauthorized persons. The device is made of three steel assemblies, one of which is fitted over a tailgate extension, using the extension as an anchor for holding the device in place. A second assembly, acting as a clamp, is attached to the first by a fixed bolt and a nut. The clamp, presses on the side wall of the pickup truck, pulling the tailgate to it. Attached to the nut is a tube that holds a lock plug. When a lock plug is inserted in the tube, the nut can not be rotated and loosened. The lock plug is a cylinder lock, locked by a key and protected against weather by a plastic cap. In design, the locking device is massive, weatherproofed and although open to access, is not susceptible to cutting, breaking or damage such as sustained in unauthorized removal, without causing damage to paint finish of the tailgate which is being appropriated without the owner'permission, and has no resale value in less than 100% perfect condition.
