Abstract: A fluid-transfer coupling device designed to couple a rigid male endpiece to a flexible female pipe and to the production method therefor. The device includes a sleeve for gripping around the pipe and locking the endpiece, the sleeve having a radially inner part surrounding an annular sealing lining mounted in abutment on the endpiece; and a metal socket having a tubular portion gripped by the pipe and ending in a collar formed by a radial step which extends in an axial end and has a radial height, the axial end being mounted inside and in contact with the radially inner part and forming the base of a groove receiving the lining, the device comprising means for fitting the sleeve to the collar and comprising a continuous peripheral projection formed in one piece with the sleeve. According to the invention the projection projects radially in abutment against the step aver most of the radial height.

Abstract: The invention relates to a composite annular seal (30) having a flexible body and rigid reinforcement (35) for a rapid fluid-transfer coupling (1), and to a rapid coupling of this type incorporating the seal. The seal (30) with a reinforcement (35) can be used for a coupling comprising a female tubular sleeve (10) and a male tubular endpiece (20) mounted inside the sleeve in order to produce overall static sealing between a recess (13) in the sleeve (10) and the endpiece (20), the seal comprising: an inner axial wing (31) having a radially inner face (31a) which has a radially innermost flexible peripheral portion (31aa) designed to be applied tightly against the endpiece; an outer axial wing (36) having a flexible radially outer face (36a) which is designed to be placed firmly against the recess; and a core (33) connecting the inner wing to the outer wing. According to the invention, the innermost peripheral portion (31aa) is convex, with a rounded shape in axial section.
