ABSTRACT:
A trailer hitch for attachment to a vehicle bumper for providing releasable coupling with a trailer coupling member. The hitch includes a coupling ball partially surrounded by an enclosure extending above the top of the coupling ball. A safety bar is received in slots formed in the surrounding wall. The safety bar, when installed, overlies the coupled arrangement of a ball joint and trailer coupling member so as to prevent their unintended separation. Further, the walls surrounding the coupling ball are pivotally mounted to the vehicle bumper and include a spring which contacts either the vehicle or its bumper to orient the enclosing walls in a preferred direction.
