Abstract
This fitting has a transverse bore (3) and, at one of its ends, a male or female threaded end to connect it immovably to one of the two parts to be joined by means of tube (6) and, at its other end, a ring-shaped chamber (5) which is coaxial to bore (3) and which, in addition to a ring-shaped watertight joint (9) and a retaining collar (8), houses a ring-shaped member (7) which has prongs (7a) slanted toward the rear (5a) of chamber (5) and pro-jecting radially into chamber (5), thus delimiting an inside diameter normally smaller than the outside diameter of the connecting tube, the purpose of this chamber (5) being to receive and retain one of the ends of tube (6) simply by inserting it to the rear (5a) of the chamber and the inside and outside diameters of chamber (5) corresponding approximately to the outside diameter of tube (6), while the outside diameter is greater than the outside diameter of tube (6) to make it possible to house the ring-shaped joint (9), the pronged member (7) and the retaining collar (8), and within which the ring-shaped pronged member is associated with a ring-shaped support (11) having an outer ring (11a) of the same outside diameter as ring-shaped pronged member (7) and an inner tubular part that has an inside diameter normally equal to or slightly greater than the outside diamter of connecting tube (6) and of which the free edge is oriented toward prongs (7a) of the pronged member (7) for the purpose of limiting, while serving as support for their swing in the direction of penetration into the wall of the tube. The inner tubular part is formed of tabs (11b) connected to ring ( 11a) mentioned above by their heel-shaped part (11c) curved radially outward.
