Abstract: A means for attaching a safety chain to a retractable ball or kingpin hitch is described. The means includes a metal face plate with an aperture therein. A first and second ring are coupled together while one or both is within the aperture such that both rings cannot simultaneously be removed from said aperture. The rings are size so that each has one large dimension that prevents the rings from passing completely through the aperture.

Abstract: A retractable ball or kingpin hitch is provided for the load bed of a vehicle. The retractable ball or kingpin hitch is provided with a movable pin mounted in a wall of the hitch for locking the ball or kingpin in an upright operational position. The locking feature assures that the retractable ball or kingpin will not be able to partially retract thereby compromising the effectiveness of the hitch and coupling when hauling a trailer.

Abstract: A hitch for mounting on the back of a vehicle for towing a trailer or other equipment. A ball is mounted on the extended end of a hook portion of the main hitch body and is adapted to receive either a lunette or hooded-type coupler thereon. A closure latch is pivotally mounted on a rear portion of the hitch body and is engageable with the ball when securing a lunette coupler on the hitch and is alternately engageable with the hood of a hooded coupler when securing such a coupler on the ball. A spring-biased first locking pawl is pivotally mounted on the closure latch and is clamped against a shoulder on the hitch body by a spring to lock the latch in closed position with a hooded coupler. A second locking pawl is pivotally mounted on the first locking pawl and is clamped against the shoulder by the spring to lock the closure latch in engaged position with the hitch ball when securing a lunette coupler thereon.
