An improved assembly composed of a hard member and a soft tube fitted onto the hard member for a medical use is formed with a plurality of projections on the side wall of a flange of the hard member. The projections project toward the soft tube side to firmly hold the foremost end part of the soft tube between the projections and a fitting portion of the hard member in a clamped state when the soft tube is fitted onto a fitting portion of the hard member. The foremost end surface of the soft tube may slantwise be cut to define a certain angle relative to the center axis of the assembly such that the foremost end part of the soft tube comes in tight contact with the side wall of the flange when the soft tube is fitted onto the fitting portion of the hard member. The soft tube may be formed with a plurality of cutouts which are arranged along the periphery of the foremost end surface of the soft tube in a spaced relationship. Each cutout preferably exhibits a V-shaped contour which defines a certain opening angle symmetrically relative to the center axis of the assembly.
L'invention porte sur un ensemble amélioré comportant un élément rigide et un tube souple, fixé à l'élément rigide, pour utilisation médicale. L'ensemble comprend une série de saillies sur la paroi latérale d'une bride de l'élément rigide. Les saillies s'avancent vers le côté du tube souple pour retenir fermement et pincier entre elle l'extrémité la plus en avant du tube souple raccordé à l'élément rigide. La surface de l'extrémité du tube souple peut être coupée en biais afin de définir un certain angle relativement à l'axe central de l'ensemble, de sorte que l'extrémité du tube souple est très serrée sur la paroi latérale de la bride lorsque le tube est fixé au raccord de l'élément rigide. Le tube souple peut comprendre une série d'entailles espacées le long de la périphérie de la surface de son extrémité. De préférence, chaque entaille est coupée en V, ce qui définit un certain angle d'ouverture relatif symétriquement à l'axe central de l'ensemble.
