Abstract
A transport lock for a clutch release system, in particular for a slave cylinder of a motor vehicle, is provided having an axially movable piston and a clutch release bearing that is connected to the piston being arranged concentrically on a housing. 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.

A transport lock for a clutch release system of a motor vehicle, the clutch release system including a piston that is movable in an axial direction and a clutch release bearing connected to the piston arranged concentrically on a housing, the transport lock comprising a retaining ring that has a collar extending outward in a radial direction mounted on the housing in an inner hollow space of the clutch release bearing, and a contact surface of the piston contacts the collar of the retaining ring, such that the retaining ring limits axial movement of the piston,
- wherein the retaining ring is fixed on the housing by snap hooks and a complementary recess,
- wherein an inner peripheral surface of a cylindrical area of the retaining ring is positioned on an outer peripheral-side housing surface of the housing, and the inner peripheral surface extends axially between the collar and the snap hooks.
