ABSTRACT:
The present invention relates to a releasable lock mechanism (10) for preventing accidental displacement of a hitch tow pin (24). The tow pin (24) is alternately released and locked in place by pivoting a cam lever (40) 180 degrees which action causes a spring biased member (28) horizontally supported by a support bracket (12) to slide forward over the hitch tow pin (24) and alternately backward away from the hitch tow pin (24) to enable the hitch tow pin (24) to be readily removed.
