摘要

The device has an O-ring joint (7) housed in an annular shoulder situated at an inner periphery of a connection endpiece (2). An elastically deformable axial locking unit (8) axially locks the O-ring joint and a male pipe section (1) at an inner part of the endpiece. The locking unit has a gripping tab (10) with an U-shaped section having external and internal branches (11, 12) that are extended in a perpendicular manner and in a same direction by two curved locking wings (13a, 13b) defining a locking clamp piece by locking the male section, and by an O-ring joint retaining ring.
