The draw bar is provided with a rearwardly opening slot that is adapted to receive therein a pin on the forward portion of the tongue connected to the vehicle to be towed. The rear leg of the U-shaped locking member is movable across the rearwardly opening slot in the draw bar to lock the tongue pin therein.
