Abstract: A clutch release bearing assembly comprises a clutch release bearing having an actuating element which defines an actuating nose, a coupling member carried by a connecting piece which is prefitted to the diaphragm or other declutching member of the clutch, and at least one resilient retaining ring for holding the coupling member permanently between a drive surface of the connecting piece and an actuating flank or thrust shoulder of a groove formed around the actuating nose. This groove is elongated away from the thrust shoulder, so that at least one axially acting resilient ring can be fitted into the groove in advance, with the thrust shoulder acting as an abutment for this ring.
