Couplings are disclosed herein. A plug of a coupling includes a plug body and a socket interface coupled to the plug body. The socket interface includes a shoulder extending axially outward from the plug body, a neck extending axially outward and radially inward from the shoulder, and a socket guide extending axially outward and radially outward from the neck.

A pipe unit coupling structure includes a first member in which a first hole is formed, a second member including a pipe unit which is coupled to the first member by being inserted into the first hole, and a third member coupled to the second member by a coupling unit. The second member has an inclined surface formed at a tip of the pipe unit. The inclined surface is configured in such a manner that, when the inclined surface is pressed against the first member when the pipe unit of the second member is inserted into the first hole of the first member in a state where the second member and the third member are coupled to each other, a force is applied from the second member to the third member at the coupling unit, in a direction opposite to a direction of separation of the second member.

A line coupling having a housing which has a tube connection piece and a housing head. A passage duct extends from a first opening, which is formed by the tube connection piece, to a second opening, which is formed by the housing head. A tube connection structure is arranged in the passage duct. The tube connection structure is connected in a form-fitting manner via first coupling means to a first end of an inner tube which extends out of the housing head through the second opening. The section of the passage duct between the first opening and tube connection structure and inner tube form a flow duct for fluid. A container is also disclosed having a container housing which forms a container hollow space and a container opening. The container opening is formed by an outwardly projecting connection piece, and has a line coupling.

A gas outlet extender allows for relocation of existing medical gas outlets to positions that are more ergonomic to care-givers at the point-of-use. In various aspects, the gas outlet extender may take one source of gas supply and provide the facility with a plurality of separate sources of that gas supply. By taking measurements of various parameters of the gas supply, an installer may obtain confidence that the gas flow for each of the plurality of separate sources meets regulatory requirements.

A wall socket (10), comprising: an inlet (64A), for connecting an inlet pipe (20A) thereto! a first push-to-release pipe-joint (16B), comprising an outlet (64B), for pushing thereinto an outlet pipe (20B), for connecting the outlet pipe (20B) thereto! a panel (12) disposed between the inlet (64A) and the outlet (64B), and extending from the first push-to-release pipe-joint (16B); and installation means (56) for installing the panel (12) to the building wall (50), attached thereto and parallel thereto, thereby disposing the inlet (64A) behind the building wall (50, and the outlet (64B) in front of the building wall (50), thereby allowing providing a removable supply to an implement (40) by the pressing of the outlet pipe (20B) into the wall socket (10), and thereby the wall socket (10) non-significantly protrudes out of the building wall (50).
