In order, in the case of a trailer hitch, comprising a ball neck, which is movable between a working position and a rest position and has a pivot bearing body arranged at a first end and a coupling ball arranged at a second end, a pivot bearing unit, which is arranged fixed to a vehicle and by means of which the pivot bearing body is received such that it is pivotal for the purpose of performing a pivotal movement about a pivot axis between the working position and the rest position, and a rotation-blocking device that is active between the pivot bearing unit and the pivot bearing body, to achieve fixing of the rotation-blocking device in the release position in the simplest possible manner, it is proposed that there run between receptacles in the rotation-blocking device blocking faces against which the rotation-blocking bodies of the rotation-blocking device are configured to abut and from which the receptacles extend, that rotation-blocking units of the rotation-blocking device and the receptacles are arranged at angular spacings from one another around the pivot axis such that, in all the pivotal positions of the pivot bearing body that are provided, including the rest position and with the exception of the working position, the rotation-blocking body of at least one of the rotation blocking units lies opposite one of the blocking faces, and thus this blocking face blocks movement of the actuation body in the actuation direction.
