  • Patent number: 4824145
    Abstract: Coupling components are disclosed for coupling together tubes and the like including male and female coupling components. The female coupling component described herein includes inner and outer tubular sections, and the inner tubular section includes an orifice having a size adapted to frictionally engage a male coupling component inserted therein. The outer tubular section is adapted to frictionally engage the outer surface of the inner tubular section, and the outer tubular section is substantially rigid, while the inner tubular section is substantially flexible as compared to the outer tubular section, so that axial movement of the outer tubular section when it is being coupled to the male coupling component carries the inner tubular section therewith.
