Abstract

A trailer hitch module for engaging a trailer tongue socket includes a base and a ball fixed to the base for engaging a socket cup. A locking arm is provided and pivotally attached to the base so that it is movable in a plane parallel to the base between a close position engaging a protruding lip of the socket in order to prevent removal of the socket from the ball and an open position away from the lip in order to enable removal of socket from the ball. A lock mechanism is provided for securing the locking arm in the closed position.
