A trailer hitch mountable on an upwardly facing surface of a vehicle capable of movement in a forward direction includes a base which can be fixedly secured to the upwardly facing surface and a coupling arrangement supported on the base and adapted to releasably grip a coupling element of a trailer. The base includes two support elements adapted to be fixedly secured at spaced locations to the upwardly facing surface, and a unitary pedestal which can be releasably fixedly secured to the two support elements. The coupling arrangement includes a hitch member having an upwardly facing surface and a slot which extends forwardly thereinto from a rear edge thereof, and two jaws supported for relative pivotal movement about respective pivot axes between a gripping position and a release position. An arrangement for actuating the jaws includes an elongate, transversely extending rod and a link element which extends between and is operatively coupled to the rod and a first of the jaws. An arrangement for effecting movement of the second jaw synchronously with and in response to movement of the first jaw includes a radially outwardly projecting coupling plate on each jaw, one coupling plate having a pin which is slidably received in a slot in the other coupling plate.
