ABSTRACT:
A coupling for flexible conduits in which the female element is constituted by a body 1 provided with an axial bore comprising internally a locking recess 2 and the male element is constituted by a tip on which is mounted a locking device constituted by an engagement element radially displaceable to engage in the locking recess of the female element under the action of a locking control device 13 constituted by a sleeve mounted longitudinally movably on the cylindrical central body of the male element, the end of said sleeve directed toward the engagement end of the male element forming a cam surface 14 coacting with the engagement element so as to displace it radially outwardly and this sleeve being resiliently urged by a spring 17 toward the locking position. A peripheral ring 18 is slidably mounted on the periphery of the male element so as, in the uncoupled position of the coupling, to come into engagement over the engagement element to maintain it in its retracted position toward the interior of the body of the male element.
