Claim:
A female element for a secured quick connection for removably joining pipes of fluid under pressure, said female element being adapted to receive a male element fitted therein along a longitudinal axis thereof, said female element including a hollow body defining a central channel and a locking means for locking said male element within the central channel when the male element is inserted therein, said locking means including at least one elongated member that is movable in translation within at least one guide channel in said body that is parallel to an axis which extends at an angle with respect to the longitudinal axis of said female element, said at least one member being provided with a cylindrical part of which one end is adapted to be engaged in a peripheral groove of the male element when the male element is fitted within said female element, wherein said one end is partially defined by a bearing surface that is concave having a radius of curvature greater than a radius of said cylindrical part and that is adapted to engage a side of the peripheral groove in the male element when the male element is fitted within said female element, said at least one member having a tab projecting radially outwardly with respect to an outer radial surface of said body of said female element and which is engaged between two spaced portions of a ring for controlling positioning of said at least one member with respect to said at least one guide channel and said central channel of said body, and said ring being mounted around said body so as to be movable in translation parallel to the longitudinal axis whereby, as said ring is moved, said tab is engaged by said spaced portions of said ring to thereby adjust a position of said at least one member along said at least one guide channel.
