<p>Stopper (1) for fluid coupling and comprising a self-locking sheath (11) designed to be slipped onto a connector (2), the sheath (11) extending about a central longitudinal axis (13), the sheath (11) comprising, on its inner surface and at a first end, a tapped portion (12) designed to engage with a mating threaded portion (20) formed on the outer surface of a connector (2) so that it can be screwed onto the latter or unscrewed therefrom by rotation about a direction parallel to the longitudinal axis (13), characterized in that the tapped portion (12) comprises at least one recess (116) parallel to the longitudinal axis (13), in projection according to a plane perpendicular to the longitudinal axis (13), the at least one recess (116) being secant with the circle of smaller diameter of the tapping (12), and in that the inner surface of the sheath (11) comprises, at a second end opposite the first end, a spindle (14) extending inside the sheath (11) in a direction parallel to the longitudinal axis (13) towards the second end of the sheath (11) as far as a free end (15) located between the first and second ends of the sheath (11), said free end (15) of the spindle (14) being designed to form a protective cover for a surface of the connector designed to engage with a filling tool.</p> |
