  • Patent number: 4629220
    Abstract: A pipe connection in which an improved method and apparatus for forming a quick-coupling connecting nipple for plastic pipe is disclosed. A plastic pipe section having an annular groove perpendicular to the axis of the pipe is disposed about the periphery of the pipe section at a longitudinal distance from the first end of the pipe section. A steel sleeve is friction fitted about the plastic pipe section and a groove is rolled about the outer periphery of the sleeve to present an annular shoulder disposed within the inner periphery of the sleeve. The shoulder of the sleeve snaps into the groove of the plastic pipe section. The other end of the sleeve is crimped inwardly into the pipe surface so that the sleeve is substantially flush with the outer diameter of the pipe section.
