An end fitting for a tube housed by a cavity and a method of installing a tube in a cavity are described which use a compression ring that defines a void having an axial extent and a radial extent. The compression ring is compressed between a bracket of the end fitting and a port of the cavity by drawing the bracket axially towards the port. This seals the port and deforms the void defined by the compression ring. The deformation of the void reduces its axial extent and increases its radial extent, thereby compressing the tube against an insert received within the interior of the tube.

The invention relates to a hose connector system (1) for use in an agricultural spreader machine (15), which system is characterized by rapid and secure assembly, and therefore economical production and high modularity.

A tube assembly for delivering a substance is provided. The tube assembly includes a tube body, a sleeve body, a joint member, a handle member and a fixing member. The tube body has a tube end portion. The sleeve body is fitted around the tube body and has a sleeve end portion corresponding to the tube end portion. The tube end portion is fitted around one end of the joint member. The handle member is fitted around the sleeve body. The fixing member is fitted around the sleeve end portion, the handle member and the joint member at the same time so that the fixing member presses a part of the handle member, a part of the sleeve end portion and a part of the joint member inwards in a manner such that the tube body, the sleeve body and the handle member are fixed relative to the joint member.

Disclosed are chromatography systems employing a releasable coupling (100) for holding a fluid tubing to a spigot, the coupling comprising: a cylindrical inner component (110) for accepting a fluid tubing (30), said inner component including a resiliently deflectable portion (118) arranged to urge an outer surface of the tubing toward a spigot; and a cylindrical collar (130) having and internal through-aperture (132) for slideably accepting the inner component, the aperture and resilient portion having complementary surface formations which in a first position of the collar mounted to the inner component provide for said resilient deflection in use, and which in a second different position do not cause said deflection, the coupling being characterized in that the collar comprises a collar flange (134) extending outwardly away from the aperture of a size allowing manual manipulation of the collar between the first and second positions. Chromatography systems employing said couplings is disclosed also.

A clamp device for a barb member having a barbed region for disposing within an end of a flexible tube having an outer surface. The clamp device includes a flexible member including a body having a plurality of finger members compressible between a first resting position and a second clamping position; at least one of the flexible finger members having a radially inwardly extending tooth; the body having a through bore and an outer surface comprising threads; the flexible member being slidable over the barbed region and the outer surface of the flexible tube; a compression member having a body having a through bore and an inner surface including threads; the compression member being slidable over the flexible member; wherein upon threadingly engaging the compression member with the flexible member, the compression member compresses the finger member against the barb member.

A tubing splicing device for repairing tubing includes a pair of housings. Each housing comprises a barrel, which is open-ended. A pipe, which is externally threaded, is positioned in and rotationally coupled to the barrel.
