For the snap connection of a clutch releaser with spring tongue ends of a diaphragm spring in a pulled-type diaphragm spring clutch, there is secured to the spring tongue ends a first ring part which comprises a radially inwardly protruding first stop ring shoulder directed axially away from the releaser. With the releaser there is connected a second ring part which comprises a radially outwardly protruding second stop ring shoulder directed axially to the releaser and is insertable, with the second stop ring shoulder leading, through beneath the first stop ring shoulder axially into the first ring part. On the side of the first ring shoulder axially remote from the releaser a radially elastic wire ring is arranged which snaps over the second ring shoulder in the insertion of the second ring part. A support ring is axially fixedly inserted into the first ring part and axially supports the wire ring on a ring shoulder in the insertion of the second ring part. The support ring is held by retaining tabs on the first ring part, each of which comprises at least one spring tongue which rests from radially outwards on the wire ring and centers the wire ring for the insertion of the second ring part.

A multi-disc clutch comprises a pressure plate, an intermediate plate and two clutch discs on both sides of the intermediate plate. A main spring urges the pressure plate towards a fly-wheel so that the clutch discs are in frictional engagement with the pressure plate, the intermediate plate and the fly-wheel. When the clutch disc is disengaged the pressure plate and the intermediate plate are lifted away from the fly-wheel. The lifting movement of the intermediate plate is effected by a release spring and is controlled by supporting the intermediate plate on a counter support which counter support is axially movable in response to the action of a clutch disengaging member. The counter support is established by a member which has an additional essential function within the clutch. For example, the counter support is established by the main spring or by a leaf spring connecting the pressure plate for common rotation with the clutch cover.
