A device for coupling a vehicle to a trailer is provided. The device includes a base having a channel and a pair of side walls. The channel includes a mouth leading into a stop. The side walls are spaced apart from each other and the channel runs generally between the side walls. A catch is pivotally mounted between the side walls. The catch includes a mounting end, a catch end, and a contact surface. The catch end is pivotable between a first position, wherein the catch end abuts against the base; and a second position wherein the catch end is displaced from the base. The tow pin engages the contact surface of the catch and pivots the catch end towards the second position. The catch end returns to the first position so as to secure the tow pin between the catch end and the stop when the tow pin abuts against the stop.
