Abstract: A quick connect tube coupling assembly includes a tubular seal member, in the form of a tubular member with an elastomer molded thereon is suitably fixed in the stepped socket bore of a tube receiving socket member, this seal member, in effect, providing the effect of two O-rings, a spacer, retainer and end seal; and a spring retainer is fixed to the socket member whereby this coupling body assembly is adapted to telescopically receive a plug tube having axially spaced apart radial upstanding annular inboard and outboard beads thereon, one of which is adapted to be engaged by the spring retainer. A tubular spring release member is positioned to encircle the tube loosely between the beads whereby the tube can be un-coupled, when desired, by moving this release member axially in a direction toward the inboard bead so as to cause the spring member to flux radially outward of the inboard bead whereby the plug tube can be removed manually from the socket member.

Abstract: Polyolefin pipe having an integral end connection. The pipe is fabricated with male and female end connections in order that the pipe may be press-fitted together with the interior and exterior forming a flush uniterrupted surface. One or more radial ribs and grooves are formed on the interior of the female connection while a registering series of ribs and grooves are formed on the exterior of the male connection. The ends of the pipe are bevelled in order that the ends pressed together engage and by the slight resiliency of the polyolefin pipe construction permit the slight expansion and contraction of the ends to provide a locking interfit of the respective ribs and grooves in the two ends. The wall thicknesses of the end connection and width of the ribs and grooves are particularly dimensioned in order that the male end may be inserted to a complete lock position without premature engagement and that should failure occur, it be at the readily observable pipe wall rather than in internal rib.

Abstract: A tube coupling adapted particularly for medical use includes three parts, namely a female tubular element 52, a male tubular element 50, and an intermediate ring 100 carrying at least one longitudinally extending latching arm 110. The ring is dimensioned to snap-fit into an external annular groove 90 on either the male or female element and the latching arm has an inwardly-extending hook portion 112 which can engage a flange 58 on the female or the male element as the case may be. This engagement holds these two elements together in an axial direction and allows them to rotate freely relative to one another.

Abstract: The device for coupling two pipes comprises a variable length assembly formed from two tubular parts, whereof the internal diameter corresponds to the internal diameter of the pipes. The tight coupling of this assembly to the ends of the pipes is brought about by compressing O-rings between a planar surface and a spherical surface by means of two nuts. The two tubular parts are then tightly joined by actuating a nut compressing a third O-ring.
