Abstract
An instant connection device for fluid conduits is provided having a general cylindrical configuration, with a base portion in the form of a ring and flexible jaws whose ends define an annular bearing surface and have on the inside a circular engagement edge. The clip is obtained from a metal sheet blank having a circular central portion extended by first and second evenly spaced lugs with radial axes, the blank being subjected to stamping operations. The clip is cheap and simple to manufacture. Furthermore, it is possible to associate therewith an elastomer block by moulding thereover forming a push ring and a seal.
Claims13
A clip for an instant connection device for a fluid conduit, particularly a semirigid tube, said clip having a general cylindrical configuration with a base portion in the form of a ring extended on one side by flexible jaws whose ends define an annular bearing surface offset outwardly, wherein an inside surface of the ends of said flexible jaws have a circular edge;
- wherein said clip is made from a metal sheet blank and said jaws are bended transversely with respect to the plane defined by the metal sheet blank therefor and have a substantially rectilinear portion adjacent to said ring, a longitudinally bent portion to form said bearing surface and an end portion slanted towards a center line of the clip, whose internal edge forms said circular edge;
- the jaws are transversally wider in a zone near their free end corresponding to the bent portion than in a zone adjacent to the base portion, so as to be flexible near the base portion and more rigid towards said free end;
- said clip further comprising lugs provided between the jaws to form outwardly directed spurs around the clip.
