Abstract: The invention concerns a ring (4) for fastening a pipe (1) to a tubular body (2). According to the invention, the ring comprises two rigid sectors (5) that are coupled to each other by at least one elastically deformable annular portion (12), the two sectors and the portion being a single part, each sector (5) having an inner face (6), protruding from which at least one anchoring stud (7) extends radially, intended to be received in a housing correspondingly provided in a wall of the pipe, each anchoring stud (7) comprising two grooves (9) extending circumferentially to either side of said anchoring stud. The invention also concerns connection means comprising such a ring.

Abstract: A quick connector comprising a female part (1) having a bore (8, 11), a male part (2) having an outer collar (6) suitable for being inserted in the bore, and a locking ring (3) mounted to slide radially in a housing (10) of the female part, which housing subdivides the bore into an inlet section (8) and a main section (11), the ring (3) being movable between a first position in which it is eccentric relative to the bore and a second position in which it is substantially coaxial with said bore, said ring being integral with a resilient member in the form of at least one tongue (12, 13) co-operating with the housing (10) to urge the ring (3) into its first position, wherein the ring (3) includes a thrust platen (9) adjacent to the inlet section (8) of the bore and projecting beside the tongue (12, 13), at least the free end portion of the tongue being of a width (L) that is less than the thickness (E) of the ring (3) minus the thickness (e) of the platen (9) measured in the same axial direction.

Abstract: A coupling device for a tube, the device comprising a body provided with a bore for receiving the end of said tube, and means for retaining the tube in the bore, which means are constituted by an elastically deformable washer that is substantially frustoconical in shape whose inside circumference is of a diameter smaller than the outside diameter of the tube and which is subdivided into a plurality of teeth, the outside portion of the washer being disposed in a groove formed in the bore. Each tooth possesses a short root portion which, at rest, extends in a radial plane, and an active portion that is inclined relative to the radial plane of the root, and each tooth is connected to the teeth adjacent thereto via small section peripheral link portions of length not less than the length of each tooth.

Abstract: A gasket for a claw or clamp quick-connection coupling, the gasket being constituted by a circularly symmetrical annular body defined by two parallel radial faces, an outer cylindrical surface surmounted by a partially toroidal bulge centered on the midplane of the gasket parallel to the radial faces, a partially toroidal inner surface also centered on the midplane, and connected to each of the radial faces via a respective chamfer-forming conical surface.
