Abstract
The connection has two inserted tubes, one of which, the outer tube (6), is enlarged in order to form a casing (8) for housing two support pads (10) which are held tightly between the two tubes and a radial projection (12) of the inner tube. A gasket (14, 15) with a section in the shape of a recumbent V and which has a cylindrical flange for bearing against the inner tube and a convex flange for bearing against the outer tube, is mounted on each of the ends of the casing (8). The two gaskets face in opposite directions and are fitted onto the pads which hold them tightly. The convex flange (18) is preferably spherical only for a part of its length. This spherical part forms the surface for rubbing against the casing and enables a relative displacement of these two members with no risk of the tightness failing.
