Abstract
A hitch, which can be rigidly yet removably attached to a vehicle-mounted sleeve, comprises a longitudinally extending member which is configured to slide into the sleeve and which locks therewith with a transverse locking device in a conventional manner. The member is divided into two sections along a plane which is inclined with respect to the longitudinal axis of the member. The sections are connected together by a bolt threading into one section while being operable from the outside of the other section. Due to the inclined plane separating both sections, tightening of the bolt causes the sections to slide in opposite directions within the sleeve until they abut and press on opposite inner walls of the sleeve, thereby eliminating play between the member and sleeve. The hitch is conceived such to prevent a user to drive without the locking device in place.
