ABSTRACT:
A hitch pin is arranged for coupling a tongue relative to a socket of a conventional hitch structure to include a central cylindrical body formed with a top plate member mounted to the body. The top plate member includes a plurality of first diametrically disposed latch members, each latch member including a concave saddle positioned at an upper end of each latch member at an upper end of a ramp of each latch member to receive a handle loop upon each saddle to withdraw a central lock rod through the cylindrical shaft. The lock rod includes an actuator plug mounted to the lock rod spaced from a lower terminal end thereof to effect displacement of a plurality of locking legs exteriorly of the shaft. The lower terminal end portion of the lock rod includes a lock rod lower end plate to capture a spring between the lower end plate and a cylindrical shaft cavity floor.
