The base attaches to a bottom side of the hitch assembly and comprises a substantially horizontal plate and two opposing vertical plates. The vertical plates define opposing apertures. The latch plate is pivots about the base plate about a substantially horizontal pivot axis. In a locked position the latch plate is substantially parallel to the horizontal plate of the base and on an opposite side of the ball from the horizontal plate. The latch assembly comprises a spring-loaded pin which pivotally connects the base to the latch plate, and locks the latch plate when substantially parallel to the horizontal plate. A lock pin extends through an aperture of the base and an aperture of the latch plate to further secure the latch plate.
