The piece (120) comprises a shell (150) covering its front face and receiving the return spring (250) and the thrust rod (130).The actuator piston (110) includes lugs (115) engaged behind the lugs (125) of the body (121), by a pivoting movement about the axis. The rotational position is blocked by a locking and guiding sleeve (180).
