Abstract
A towing device for vehicles comprises a transverse support, which is mounted at the rearward end and has a receiving part for the releasable holding of a ball neck with a coupling ball. An end part of the ball neck is inserted from below into the receiving part and is non-rotatably held by a locking mechanism. During the releasing of the ball neck, this ball neck can only cover a defined falling course, due to the provision of a catching device, having a transversely extending pin, which penetrates the ball neck and projects beyond it on both sides, and further has a catch hook located underneath the ball neck. The catch hook has a stationary upper part and a swivelling lower part, which is connected with the upper part, the lower part, which cooperates with a spring element, having hook portions for receiving the projecting portions of the transversely extending pin located above it.
