The trailer hitch has a pair of tubular housings 22 and 23, a coil compression spring 29 in each housing, and a cable 30 or 31. Each cable is telescopically slidable with respect to its housing, through its spring 29, and its proximal end 45 is connected to the inner end of the spring by the cable/spring connector 32. When the hooks 49 at the distal ends of the cables 30 or 31 are disconnected from the towing vehicle, the springs urge the cables into the housings.
