Abstract: A self-latching hitch device comprising a bracket that fits around a hitch receiver, a housing containing a pull pin, and a biasing member urging the pin to a closed position when the pin of the device aligns with the pull pin holes in the hitch receiver and the pull pin holes in a ball mount shaft, such that the device can be placed on a hitch receiver when the receiver holes and ball mount shaft holes are not in alignment, the ball mount shaft can be moved longitudinally with respect to the hitch receiver, and the device pin will lock the ball mount shaft into position with respect to the hitch receiver when the holes of the ball mount shaft and hitch receiver come into alignment.
