a) Units for holding and wedging and assembly formed of such units. b) Unit characterised in that it includes at least three wedges (5, 6, 7) housed so that they can move axially (xx, yy, zz) in bores (2, 3, 4) of the housing (1), these wedges (5, 6, 7) bearing on one another via an intermediate member (8) which can move with a combined movement in the direction of movement of each of the wedges (xx, yy, zz), this transmission member (8) interacting with each of the wedges via a contact connection with a cam and follower member (58, 85, 68, 86, 77, 87) so as to induce, in the transmission member (8), the loads exerted at the moment of tightening onto the wedges (5, 6, 7). <IMAGE>
