Abstract
A control valve retaining element (22) for a brake booster (10) has a hollow cylindrical base member (28) and a first retaining collar (30), which is connected to the base member (28) and has at least one side wall for supporting a bellows end (20). To enable such a retaining element to be manufactured less expensively and positioned easily and securely on an actuating rod (16) of a brake booster (10), a second retaining collar (36) extends radially inwards from a first end of the base member (28) and in peripheral direction, wherein the second retaining collar (36) comprises a first lateral face (38) for cooperation with a stop (44) of the actuating rod (16) and a second lateral face (40) lying opposite the first lateral face (38) for cooperation with a compression spring (46).
