The device and assembly provides a structure having two ball-shaped ends that are integrally formed as a single structure. With one of the balls inserted into a trailer coupler, the clamping device of the coupler can be locked as it would be when connected to a trailer hitch ball. The device and assembly of the present invention is intended to be a “filler” structure which prevents theft of a trailer using the coupler because the coupler cavity is filled and locked. Preferably, the ball ends are made of a single piece of hard plastic, nylon or metal material (although plastic is preferred for a light-weight structure) and connected to a cable that allows the device to be suspended from the coupler for use when necessary. Each ball is sized in accordance with at least two different sizes of hitch balls that are used in the coupler market. |
