Abstract:
A coupling device is provided having a female coupling engageable with a male coupling and a ring interposable between the couplings and provided with retaining means. A gasket is housed in the female coupling and held in position by the ring. The retaining means axially holds the ring to the female coupling and has two windows spaced apart in the circumferential direction over the body of the ring. The complementary retaining means of the female coupling has two lugs projecting from the tubular body constituting the female coupling. Each window houses an elastically deformable tongue having its free end co-operating with a longitudinal edge of the window to provide a housing within which one of the lugs becomes inserted in the engaged state of the female coupling and of the ring, and the retaining means holds the ring to the male coupling having two through openings arranged in the body of the ring and a locking member.
