Fluid connector with locking ring
First Claim
1. A female connector, for fluid connection, adapted for receiving a male connector having a retaining external annular rim, the female connector comprising:
- a body with a bore of axis X,a housing forming a slide extending generally within a transverse plane YZ perpendicular to axis X,the housing comprising two parallel lateral grooves and the housing being open at least at one of its ends in the direction Z of the slide, anda deformable locking ring distinct from the body, adapted to be inserted into the housing and to lock the male connector in the coupling position,the deformable locking ring comprising two diametrically opposed first arched portions, concave as viewed from the axis X, and two diametrically opposed second arched portions of inverse curvature, meaning convex as viewed from the axis X, each of said second arched portions being interposed between said two first arched portions,the second arched portions being adapted to flex outward during insertion of the male connector and to abut against the retaining external annular rim to prevent withdrawal of the male connector, whereby, after locking the male connector in the female connector, a definitive locking is obtained.

Abstract
A female connector (1) configured to receive a male connector (2), having an annular exterior retaining rim (24), the female connector including a body (10), and a transverse slide (4) forming a housing, the housing (4) including two lateral grooves (41,42), the female connector including a separate deformable locking ring (3) capable of being inserted in the housing and of locking the male connector in the coupling position, the locking ring including two first concave arched portions (31), as viewed from the axis, and two second arched portions (32), with inverse curvature, i.e. convex when viewed from the axis, the second arched portions being capable of flexing towards the exterior during insertion of the male connector and capable of abutting on the external annular retaining rim and preventing withdrawal of the male connector, whereby after locking of the male connector in the female connector a definitive locking is obtained.

12. A deformable ring of molded plastic, suitable for use as said deformable locking ring of a female connector, the deformable ring extending annularly around a central axis and comprising:
-
two diametrically opposed first arched portions, concave as viewed from the central axis, two diametrically opposed second arched portions of inverse curvature, meaning convex as viewed from the central axis, each of said second arched portions being interposed between said two first arched portions, and outwardly extending projections arranged at the joining between the first arched portions and the second arched portions, for retaining the deformable locking ring in a housing of said female connector.
