A device for locking a spare tire wheel which is mounted vertically on the back of a vehicle. The spare is mounted on studs that project from the back of the vehicle and is fastened in place with stud nuts. The device comprises three major metal parts: One part is a rectangular section tube that fits over one of the studs, with the stud protruding up through it. Another part is a locking assembly shaped to hold the stud nut in place. This assembly is inserted in the tube until it grasps the stud nut. The third part is a cylindrical lock plug which is inserted through a hole in the top of the tube and also through a hole in the locking assembly. Turning a key in the lock plug releases a lock pin that prevents removal of the lock plug. The stud nut can not now be accessed for removal, and the spare tire wheel is prevented from being removed by unauthorized persons.
