A blocking device blocks rotation of the ball head with respect to the towing vehicle. A braking device (69) e.g. friction brake and/or piezo-electric braking device, brakes rotation of the ball head with respect to the towing vehicle. A coupling ball and a ball support (15c) are formed fixedly or integrally connected with each other. The ball support is rotatably mounted at a coupling arm (14c) around a rotational axis by the bearing.",
