An improved coupling hitch especially for a tractor in agricultural applications has the hitch socket on the trailer drawbar gripping the hitch ball (2) over not more than 180 deg to ensure unimpeded coupling and release. The socket is further fitted with a locking profile (10) operated by a control, to contact the towing ball and together with the socket provide a secure grip of more than 180 deg on the ball.
