ABSTRACT:
A trailer locking device adapted to be fixedly inserted into the cup of a trailer hitch. The locking device, which can be in the shape of a ball, includes an outer shell made from a plurality of movable plates. Once inserted into the cup of a trailer hitch, a locking mechanism is used to separate or otherwise move the plates apart in order to expand the size of the outer shell. Once locked into position, the trailer locking device becomes lodged within the cup of the trailer hitch preventing a trailer in association with the trailer hitch from being stolen.
