Abstract

La présente invention concerne un dispositif d'accouplement (1) destiné à relier fluidiquement et mécaniquement deux éléments (2, 3) guidant un flux de fluide (39), en particulier dans un véhicule automobile. Le dispositif d'accouplement comprend une bague extérieure (4) qui est formée ou peut être appliquée sur un élément (2), une bague intérieure (5) qui est formée ou peut être appliquée sur l'autre élément (3) et qui peut être insérée axialement dans la bague extérieure (4), et une bague de couverture (7) qui est disposée à l'extérieur sur la bague extérieure (4) de manière à pouvoir tourner dans la direction périphérique. Une manipulation simplifiée est possible à l'aide d'au moins un levier à cran (8) qui est disposé sur la bague extérieure (4) de manière à pivoter autour d'un axe de pivotement (9) s'étendant perpendiculairement à la direction axiale et perpendiculairement à la direction radiale, la bague intérieure (5) présentant un contour à cran (10) dans lequel le levier à cran (8) s'encliquette quand il est inséré et fixe la bague intérieure (5) axialement à la bague extérieure (4), le levier à cran (8) pouvant être déplacé, par rotation de la bague de couverture (7) d'une position de verrouillage dans une position de déverrouillage, d'une position d'arrêt dans une position de libération dans laquelle le levier à cran (8) libère axialement le contour à cran (10) de sorte que la bague intérieure (5) puisse être extraite axialement de la bague extérieure (4).
