Load carrier for retractable hitch

The device for the transporting of loads on vehicles with ball couplings has a housing (A) in which is accommodated a ball head, and means of clamping (B,C,D) by which the device is fastened on the ball head. The means of clamping are in the form of at least two clamping jaws which each have a recess conforming to the shape of the ball head. The clamping jaws have a handle for their tightening up or release and in a fully completely assembled state of the device is inaccessible and so secure against inadvertent release.
