ABSTRACT:
A hitch lock for disabling hitching couplers of trailer vehicles. A reversible keeper member includes a base portion and an extended portion projected forwardly from the base portion at an obtuse angle. The base portion includes an aperture through which is inserted an ear that is mounted on a tongue of the trailer vehicle near the hitching apparatus. A substantially U-shaped lock guard, including an ear-receiving aperture in the web portion thereof, is inserted over the ear adjacent the base portion. A shackle of a padlock is inserted into a throughbore aperture of the ear between the leg portions of the lock guard. The extended portion of the keeper member obstructs the hitching coupler such that a trailer vehicle attached to a tractor vehicle cannot be disattached and, when reversed, an unattached trailer vehicle cannot be attached to a trailer vehicle. The hitch lock works effectively with both ball and socket couplers and with pintle ring couplers.
