Abstract
A transmission joint consists of two drive shafts connected by an articulated mechanical connection. This connection is protected by an elastic socket, such as a sealing bellows, connecting the shafts. One end of this socket is multilobed to cover upon contact a multilobed element of the articulated mechanical connection and works with a tightening element of the collar type that surrounds the multilobed end of the socket. The multilobed end of the protective socket has, to the right of the zones of greater thickness of the multilobed wall, a reinforcement of the thickness to obtain an external radial bulge of the wall of the socket, at least when mounted on the multilobed connection element. The bulge works with the collar type tightening element to balance the tightening forces between the thin and reinforced portions of the multilobed wall.
