Abstract

La présente invention concerne un ressort d'arrêt (6) servant à la fixation axiale d'un élément enfichable tubulaire (4) d'un raccord de conduite de fluide (1) dans un élément douille (5) du raccord de conduite de fluide (1), présentant un élément en fil métallique (13) qui s'étend dans une direction circonférentielle (11). Sur l'élément en fil métallique (13) sont ménagées plusieurs zones d'engagement (14) qui sont réparties dans la direction circonférentielle (11) et qui, lorsque le ressort d'arrêt (6) est utilisé dans le raccord de conduite de fluide (1), s'engagent chacune radialement vers l'intérieur dans une partie rainure annulaire (10) formée sur l'élément enfichable (4) à travers une ouverture de passage (12) ménagée sur l'élément douille (5), pour fixer radialement l'élément enfichable (4) dans l'élément de douille (5). Au moins deux desdites zones d'engagement (14) présentent chacune des sections droites (15) orientées vers l'intérieur, dont les droites médianes longitudinales (16) se coupent respectivement en un point d'intersection (17). Les points d'intersection (17) des zones d'engagement (14) se situent à l'intérieur d'une zone de convergence (18). On obtient une plus grande stabilité si la zone de convergence (18) se situe dans une zone intérieure (19) du ressort d'arrêt (6) qui est délimitée radialement par les extrémités intérieures (20) des zones d'engagement (14).
