A coupling part for a hose coupling, a hose coupling provided therewith and method for coupling a hose or hose part. The coupling part includes an annular element; a number of hook-like coupling elements arranged at or on the annular element and configured to engage on a corresponding coupling element of a corresponding coupling part for the purpose of forming a coupling; and a wall surface provided on the inward directed side of the hook-like coupling element and provided at an angle of chamfer to the main throughflow direction of the coupling part.

A female pipe coupling member includes a coupling body and a sleeve 138 disposed around a cylindrical peripheral wall portion of the coupling body. The sleeve has a locking element receiving hole extending therethrough from an inner peripheral surface to an outer peripheral surface. When the sleeve is in a locking element releasing position where the locking element receiving hole radially aligns with a locking element, the locking element is received in the locking element receiving hole to assume an unlocking position. The locking element receiving hole is configured to block the locking element from passing therethrough radially outward and thus holds the locking element in the unlocking position from outside.

An adapter for selectively providing fluid to a device from one of multiple fluid sources has a body with a first inlet for connecting a first one of the multiple fluid sources to the device and a second inlet for connecting a second one of the multiple fluid sources to the device. The adapter also includes a handle that is movably coupled to the body and includes an access control element. The handle is configured to secure the body to a device when the adapter is in either of a first position or a second position that is rotated relative to the first configuration. The access control element obstructs access to the second inlet when the adapter is secured to the device in the first position and the access control element obstructs access to the first inlet when the adapter is secured to the device in the second position.

A connection device has a line portion having, at its end, a radially outwardly projecting abutment flange for abutting against a corresponding abutment flange of a further line portion which is to be coupled to the line portion, and a ring-segment chain comprising a plurality of ring segments connected to one another in a pivotable manner in a common ring plane, wherein the ring-segment ends which form the chain ends can be latched to one another to give a ring-form connection clamp. The line portion is designed in the form of a tubular connection stub with first thread means spaced apart axially from the abutment surface of its abutment flange and in that each ring segment has a radially inwardly projecting clamping flange and second thread means, which are spaced apart axially from said clamping flange and correspond to the first thread means.

Connector assemblies, connector bodies, fluid systems including connector assemblies, and procedures for making fluid connections are disclosed.

Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device while a locking ring of the first aseptic device is in an indexed initial position, rotating the locking ring to a secured position in which a compressive force is created and in which a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device can removed thereby resulting in a first a first sealing member of the first aseptic coupling device sealing with a second sealing member of the second aseptic coupling device to form a sterile fluid passageway.

A gas stem assembly comprising a vent tube having at least one protrusion extending in a radial direction, a receiver having a hole through which the vent tube extends and having at least one mating recess configured to interact with the at least one protrusion, and a spring configured to bias the at least one protrusion toward the receiver.

An aseptic coupling device includes: a main body defining a front face; a membrane coupled to the front face, the membrane including a first portion coupled to the front face and a second portion folded over on the first portion; and a low friction member positioned between the first and second portions of the membrane.
