The catch has a recess in form of a guide groove (5) or an overlaying part in the form of a rotary protection bolt arranged at a clutch arm (1). The arm intervenes a locking pin (9) in the groove or a gripping arm at the bolt when falling after release of a locking device (6) holding the clutch arm at a vehicle. The gripping arm or the locking pin swivel in or out to and fro into a drop distance of the clutch arm for activation/deactivation, where the drop distance of the clutch arm is short in the range of few centimeters.
