ABSTRACT:
A pivotally mounted coupling guard, extending over a ball engaging socket of a trailer hitch to preclude disengagement of the socket from the ball, is locked in place to deter unauthorized disengagement of the socket from the ball and theft of the attached trailer. A lock module penetrably receives and locks therein essentially all of the extending ends of both the pivot pin and the retaining pin of the coupling guard to preclude unauthorized pivotal movement of the coupling guard.
