ABSTRACT:
The anti-theft trailer assembly includes a trailer body, a cab connector in the form of a hitch post depending from the front portion of the trailer and having a generally central annular recess therein, and a lock releasably secured in the annular recess. The lock has a lock body with two generally U-shaped halves, each with a pair of spaced arms, one set having depending posts releasably secured in the other set of arms. The lock halves define a central transverse opening which receives the recessed portion of the hitch post, rendering it unusuable by filling it and slightly bulging from it. The lock cannot be pried out from the recess. The locking mechanism includes a locking plate, the ends of which fit into opposed notches of the lock posts, and a key lock component fixedly secured to the plate and rotatable by a key to move the plate out of the notches to unlock the halves against the biasing force of a spring bearing against the plate. The lock is simple, durable and efficient.
