Clip fasteners for attaching gaskets or gasket-like devices to a mounting surface and its installation method as well as the equipments

A clip fastener for attaching gaskets and gasket-like devices to a mounting surface consists of a single strand of resilient metal wire, said fastener comprising a mounting surface engagement head (201), a neck (202) and a base (207) perpendicular to the plane of the head (201) and attached to the neck (202);

• the head (201) with an apex (204) and a pair of shoulders (205) extended from the apex (204) to the shoulders (205), wherein one of the shoulders twists into an end of the metal wire (206) and the other one of the shoulders twists inward to be an adjacent point to the end of the metal wire, forming into the neck (202) at the thinnest portion of the shoulders;
• the metal wire is slightly tilted downwards from the neck (202) and then helically winds into an annular base (207), the neck (202) locates over the base (207);
• there are wave shaped protrusions on the base (207), and the plane of protrusions is perpendicular to the base (207);
• another end (209) of the wire close to a beginning (210) of the base annulus but left with space is in the same plane as the base (207).
