A trailer hitch for resisting inadvertent separation of a trailer tongue coupler from a vehicle's hitch ball. The trailer hitch includes a sleeve, a retainer rotatably disposed within the sleeve and including: a rod rotatably disposed within the sleeve, a displacement member coupled to the rod and extending radially therefrom, and a retaining member coupled to the displacement member and resisting inadvertent separation of the trailer tongue coupler from the vehicle's hitch ball when the retaining member is axially disposed adjacent the vehicle's hitch ball. The sleeve includes a shaft coupler removably coupleable to the vehicle. Further, there is a hitch shaft substantially parallel to the sleeve. Also, the displacement member includes a bent rod and the retaining member includes a disk. Still more, the rod is rotatably coupled to the sleeve by a pair of apertures and a bolt.
