Beschreibung
Zusammenfassung:	The coupling comprises a first component (3) attached to a first tube (6), and a second component (2) surrounding a second tube (5) with an end member (51) which is expanded with the aid of a lock and release system (4). The two components (2, 3) have a spring (44) to compress the expanded member against a sealing surface (31) of the first component (3) with the aid of a sealing member (20) of the second component. The contact surface of the expanded member forms a seal ring (11) of variable diameter. Raccord (1) de deux tubes (5, 6) par coopération d'un premier élément (3) solidaire d'un premier tube (6), et d'un second élément (2) formant une couronne pour un second tube (5) muni à son extrémité d'une partie expansée (50, 51, 52, 53), à l'aide d'un crabot (4) comprenant un ressort (44) assurant la compression de ladite partie expansée caractérisé en ce que ledit crabot (4) forme une première bague cylindrique de guidage (40) coulissant sur ladite paroi extérieure cylindrique (32) dudit premier élément (3), avec un évidement (41) formant cage pour ledit ressort (44), une seconde bague cylindrique de guidage (42) solidaire de ladite première bague (40) et coulissant sur ladite paroi externe (21) dudit second élément (2), et comprend un moyen de verrouillage / déverrouillage (43) dudit second élément (2) avec ladite seconde bague cylindrique (42).
