A releasable coupling device (10) of the type set forth, characterised in that the cam-type of interengagement between the inner surface of the cap member (13) and the outer surface of the gripping member (18) comprises: a primary arrangement of cams (20) and guide surfaces (22) engageable therewith, upon rotation of the cap member to the clamping position, so as to deform the gripping member (18) radially inwardly to gripping engagement with the outer periphery of the second tubular component; and a secondary arrangement of cams (25) and guide surfaces (26) engageable therewith, upon rotation of the cap member to the clamping position, so as to take up any radial clearance (A) which may develop between the inner surface (24) of the cap member and the outer surface (23) of the gripping member (18) as a result of radial inward deformation of the gripping member by the primary arrangement of cams and guide surfaces.
L'invention concerne un dispositif (10) de raccord desserrable du type décrit, caractérisé en ce que l'engagement du type d'une came de la surface interne de l'élément capuchon (13) dans la surface externe de l'élément de prise (18), comprend: un premier assemblage de cames (20) et de glissières (22) engageables dans les premières, après rotation de l'élément capuchon en position de serrage, de façon à déformer l'élément de prise (18) vers l'intérieur, dans le sens radial, jusqu'à obtenir un engagement solidaire avec la périphérie externe du second élément tubulaire; ainsi qu'un second assemblage de cames (25) et de glissières (26) engageables dans les premières, après rotation de l'élément capuchon en position de serrage, de façon à absorber tout jeu radial (A) pouvant se développer entre la surface interne (24) de l'élément capuchon et la surface externe (23) de l'élément de prise (18) comme conséquence d'une déformation vers l'intérieur, dans le sens radial, de l'élément de prise, due au premier assemblage de cames et de glissières.
