A fluid flow connector including a housing assembly, having a first end and a second end arranged along a common longitudinal axis, and a resilient fluid flow conduit member having a forward end, disposed alongside the first end of the housing assembly, formed with a selectably closable slit and with at least one side opening. The resilient fluid flow conduit member is positioned in a closed position wherein the slit is closed but the at least one side opening is open and in an open position, allowing the slit to open and leaving the at least one side opening open, whereby when the resilient fluid flow conduit member is in the open position, the selectably closable slit and the at least one side opening each provide a fluid flow pathway between an interior of the resilient fluid flow conduit member and the first end of the housing assembly.

A hose connector assembly is an apparatus that serves as a rotatable pipe joint to allow the formation of a fluid connection between separate plumbing parts, such as two hoses or a hose and a water spout. The apparatus includes a hose adapter, a screw cap, an intermediate fitting, a proximal annular brace, and a hose connector. The hose adapter allows the secure connection of the apparatus to a plumbing part, such as a spout, a hose, or other pipe fittings. The screw cap allows the rotation of the intermediate fitting to enable the rotation of modular subassemblies of the apparatus about the intermediate fitting. The intermediate fitting also allows the detachable connection between the modular subassemblies of the apparatus. The hose connector facilitates the attachment of the apparatus to the target hose end. The proximal annular brace ensures the connection of the hose connector to the target hose end.

A flexible connection pipe for a cryocooler includes a connection hose that includes a flexible pipe which is provided with a pipe end portion and a flexible tube which is provided with a tube end portion coming into close contact with the pipe end portion and which is inserted into the flexible pipe and a connection adapter that connects the connection hose to a constituent element of the cryocooler, the connection adapter being adjacent to the tube end portion and being fixed to the pipe end portion.

A coupling device for mounting onto the spout of a faucet is disclosed. The device is connected or connectable to a hose and includes an elastomeric sleeve and a clamp assembly. The clamp assembly includes a housing and a pressure applying member. The housing has a cavity holding the sleeve between a back wall and the pressure applying member. The sleeve receives the externally threaded spout. The pressure applying member is movable to a closed position to compress the sleeve tightly about the spout to releasably secure the device to the faucet. The pressure applying member is also movable to an open position to release the spout from the sleeve. Also disclosed is a cap device for releasably sealing an externally threaded mouth of a bottle or other hollow vessel and making use of an elastomeric sleeve and a clamp assembly similar in many respects to the coupling device.

A connection structure includes: a first pipe member including a first fixing unit, a housing section, and an area closer to the second end side than the first fixing unit, the area being covered with an outer layer of the housing section; and a second pipe member including a two-stage structure including a first part, and a second part, a second fixing unit capable of being fixed to the first fixing unit, the second fixing unit being provided on an inner peripheral surface of the first part, and a positioning unit. The first pipe member is inserted into the second pipe member to determine positions with respect to each other by the positioning unit, the first and second fixing units are fixed to each other, and the outer layer is pressed and fixed to the first pipe member by the second part.

The present invention relates to a shower head adapter connected between a main shower head body and a hose. To this end, the shower head adapter according to one embodiment of the present invention comprises: a body part, which has one side connected to the inner circumferential surface of the inlet side of a main shower head body and the other side connected to a hose, also has a first circular groove formed along the outer circumferential surface thereof, and forms a flow channel passing through the other side; a main body connecting part, which shares the flow channel with the body part and has an end on the other side protruding inwards from the inner circumferential surface thereof, wherein a part of the inner circumferential surface is coupled to the outer circumferential surface of the inlet side of the main shower head body; and a snap ring, which is inserted in the first circular groove, and the diameter of the outer circumferential surface of which is larger than the diameter of the protruding inner circumferential surface of the main body connecting part, and which thus prevents the main body connecting part from being separated from the body part in case of a force acting in the direction from the other side to the one side of the body part.
