The clutch designed to give increased life has a dished cover (1) with a support ring (2) mounted inside its rim, for a plate spring (3). The support ring has set of fingers (5) passing through the plate spring, and is secured to the cover by riveting. The plate spring is held in contact with the pressure plate (4) housed inside the dished cover. Each finger has a central locating stem for the plate spring, a spigot for riveting at one end, and a supporting surface at the other end. This surface is hardened by e.g. a chromium surface, or by nitriding. This surface can be inductively hardened, and is harder than the material of the cover plate. L'invention a trait à un accouplement à friction. Elle a pour objet un accouplement dans lequel, en vue du montage pivotant d'un ressort à disque, est prevu, d'une part, un appui côté couvercle, et d'autre part un appui sur le côté écarté du couvercle, qui est porté par des organes de retenue prévus sur le couvercle et traversant le ressort à disque, ce dernier étant serré élastiquement entre les appuis. Les organes de retenue possèdent sur la région de support 5a pour l'appui 6, au moins superficiellement, une dureté 7 supérieure à celle dans le reste de l'organe de retenue. Application : embrayage.
