ABSTRACT:
A base member for attachment to a vehicle to be towed comprising elongate upwardly converging guide walls of equal length to slidably receive a drawbar therebetween for movement between retracted and advanced positions relative to the base member. The drawbar has a socket element at its forward end for coupling with a ball member on a towing vehicle and a sliding pivot pin at its rear end for guiding the drawbar along the length of the guide walls and permitting swinging of the drawbar laterally to position the socket element in alignment with the ball member without having to maneuver the towed or towing vehicle. The sliding pivot pin snaps into notches in the base member when the drawbar is moved into its retracted position to lock the drawbar in driving relation to the base member.
