Embodiment Construction

[0039] In the example shown, the female connector 1 is connected to the male connector 2 by a coupling movement during which the male connector is inserted along the axis X into the female connector.

[0040] For each of these connectors, in this document the term "front" means the part closest to the complementary opposing connector and the term "rear" means the part furthest from the opposing connector .

[0041] The female connector 1 includes a pipe end piece 17 at its rear for accommodating a hose (not shown) and an interface at its front for coupling with the male connector 2; The coupling interface is described.

[0042] Similarly, the male connector 2 includes a tube end piece 27 at its rear for receiving a hose and an interface at its front for coupling with a female connector, as will be discussed further below.

[0043] It should be noted here that the female and / or male connectors can have flanges on their rear for connecting to containers, such as soft bags, ins...

Abstract

A female connector (1) capable of and intended for receiving a male connector (2), having an annular exterior retaining rim (24), the female connector comprising a body (10), and a transverse slide (4) forming a housing, the housing (4) comprising two lateral grooves (41,42), the female connector comprising 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 comprising 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.

Description

technical field [0001] The present invention relates to fluid connectors for biopharmaceutical applications, especially for fluid connections or couplings that connect a female connector to a male connector to connect one fluid line to another A tube or connection to a container. Background technique [0002] More specifically, hoses or tubes and receptacles or containers are used in the field of biopharmaceuticals to transport and contain various biopharmaceutical substances, usually with the necessary precautions of sterility. [0003] In biopharmaceutical applications, fluids are transported and stored at low pressure, usually below 10 bar, and mostly below 2 bar, preferably at a pressure close to atmospheric pressure. [0004] With certain substances, it may be necessary to temporarily ensure adequate sterility after connecting the various components (tubing and / or containers). For this purpose, it is convenient to use a male-female connection which cannot be decoupled...
