• Retainer including the snap hook a large axial space is needed.
• the piston should be permanently fixable on the bearing, with an axial space should be as low executable.
• a compound of the piston to the bearing should be inexpensive and easy to produce.
• a slave cylinder for a clutch actuator having a piston and a

• the transport lock can be a permanent, not achieve separable connection of the release bearing with the piston. In this case, a non-cutting connection, wherein at the same time axial space can be saved.
• the slave cylinder is a release system.
• the slave cylinder is a release system.
• the piston is designed as a cylinder piston.
• Bending means bending, bending, deforming or flanging. Beading is preferably a forming and joining technique in sheet metal processing. Beading is preferably understood as meaning a right-angled bending of the edge of round or oval sheets with a hemming device, in particular a hemming machine, or by hand.
• the projecting portion of the piston is designed as a counterpart to the second end of the transport lock. After a bending of the second end to the projecting portion encloses or surrounds the second end of the projecting portion. This allows the second end of the transport lock in a simple manner to lead around the projecting portion of the piston and fix it.
• the second end is bent approximately at right angles to its initial state.
• the second end is at an angle of 80 ° to 100 °, more preferably at an angle of 90 °, with respect to its initial state
• the second end is hook-shaped. This allows embracing the transport lock on the cantilevered area as soon as the second end is bent relative to its initial state.
• the second end has a hook-shaped geometry.
• the second end has two legs, with an angle between the legs measuring 75 ° to 105 °. Most preferably, the angle measures 90 °.
• the transport lock is a retaining ring.
• the retaining ring is designed as a retainer ring or as a Nutenring.
• a contact surface of the outer ring is located on a first side of the center piece of the transport lock. Further, a contact surface of the piston abuts on a second side of the center piece.
• Cross-sectional weakening introduced into a region between the middle piece and the second end in the transport lock.
• the cross-sectional weakening is a cross-sectional taper.
• a slave cylinder can be produced with a transport lock, with a permanent, non-separable connection from the release bearing and piston can be achieved.
