An air spring having a flexible sleeve is mounted between a pair of movable support components to maintain the components in a spaced relationship. The flexible sleeve has a hollow interior which forms an internal fluid chamber. A connector is mounted in one end of the sleeve and receives a tube for controlling the flow of fluid into and out of the chamber. The connector has a main body molded into the sleeve end and a collet member telescopically rotatably mounted in a hollow interior of the main body. The collet member has a plurality of flexible fingers which grip the end of a tube when inserted therein and have one-way barbs which grip the tube to prevent it from being pulled out once it is inserted within the connector. An elastomeric seal is mounted within the body to provide a fluid seal between the tube and body interior.
L'invention concerne un ressort pneumatique (1) comportant un manchon flexible (6, 7, 8) monté entre deux éléments de support mobiles (2, 3), qui permet de maintenir ces derniers à une certaine distance l'un de l'autre. Le manchon flexible comporte une partie interne creuse formant une chambre à fluide hydraulique (9). Un raccord, monté sur l'un des manchons, reçoit un tube (14) permettant de contrôler le débit du fluide entrant dans la chambre et sortant de celle-ci. Le raccord comporte un corps principal (16) moulé dans l'extrémité du manchon et un élément de douille (32) monté de façon rotative et télescopique dans une partie interne creuse (22) du corps principal. L'élément de douille est composé d'une pluralité de griffes flexibles (33) s'agrippant à l'extrémité d'un tube inséré, et des crochets unidirectionnels (37) plantés dans le tube, qui l'empêchent d'être arraché une fois en place dans le raccord. Un joint en élastomère (30), fixé sur le corps, assure l'étanchéité entre le tube et la partie interne du corps.
