A coupling device which is adapted to couple a towed vehicle such as a trailer to a towing vehicle such as a truck. The coupling device is designed to be used with many conventional receiver structures that are mounted to towing vehicles, the receiver structures being of the type that normally receive an elongated square insertion member which carries a ball hitch. The coupling device of the present invention is adapted to be inserted into the same receiver structure and is designed to carry a ball hitch, but the coupling device has many advantages over the conventional receiver insertion member because it is extendable in a longitudinal as well as lateral direction so that the towing vehicle does not have to be perfectly aligned with the hitch of the towed vehicle in order to couple the two together.
