<p>Fastening coupling for a ringed tube, comprising at least one sleeve (18), the inside diameter of which is at least equal to the largest outside diameter of the ringed tube, inside which one end of the ringed tube becomes housed, as well as a fastening ring (10), in which the sleeve (18) includes at least two circumferentially aligned orifices (28), each comprising a wide part (30) and a narrow part (32), these parts being adjacent and intercommunicating; the ring (10) is circumferentially discontinuous and radially deformable and is provided with at least two tenons (12) projecting inwards, each one comprising a narrow base (13); the ring (10) can be applied around the sleeve (18) so that each tenon (12) passes through the wide part (30) of an orifice (28) and engages in the ringed structure of the tube (48) so as to retain it axially inside the sleeve (18); it being possible, by rotating the ring (10), to fit the narrow base (13) of each tenon into the narrow part (30) of an orifice (28) so as to prevent any radial movement of the ring (10). <IMAGE></p> |
