A diaphragm clutch mechanism comprises a cover, at least one pressure plate, a diaphragm and assembly apparatus securing the diaphragm to the cover. The assembly apparatus comprises on the one hand, retaining members which are coupled to the cover and which have an axial part passing through the diaphragm and an end wing bent over with the aid of a notch in the axial part and defining with the said axial part a wedging elbow, and, on the other hand, a ring wedged in the wedging elbow. According to the invention, the ring is of frustoconical shape with a rounded outer ridge forming a secondary abutment and with inner ridges in contact respectively with the axial part and the end wing of at least one of the retaining members. The invention is particularly applicable to diaphragm clutches for motor vehicles.
