TRANSPORT LOCK, IN PARTICULAR FOR THE PISTON OF A CLUTCH RELEASE BEARING
The invention relates to a transport lock for a clutch release system, in particular for a slave cylinder of a motor vehicle, an axially movable piston and a clutch release bearing that is connected to said piston being arranged concentrically on a housing. According to the invention, in order to lock the piston or the clutch release bearing during transport, a retaining ring which has a collar that extends outwards in a radial direction and which is secured on the housing in an inner cavity of the clutch release bearing is provided. A contact surface of the piston lies against the collar of the retaining ring in such a way that the retaining ring restricts the axial movement of the piston.
