Abstract
A towing device has a ball neck equipped with a ball head that can be moved by a spindle adjusting element back and forth from an operative position into an inoperative position. The ball neck is arranged in a rotary block which is swivellably held in a carrier part. For supporting the ball neck in all possible loading directions, supporting surfaces, a torsion stop as well as a detent pawl are provided so that a movement of the coupling neck is avoided when forces act upon it, and a precise position is ensured in the operative position.
