ABSTRACT:
A quick connector includes a body, a restricting ring and a constrictor. The body has a central through hole for liquid to flow through, a constrictor groove in the central through hole for an O-shaped ring and the constrictor to fit therein, and plural petals on an upper end. The restricting ring has a center hole, an inner circumference and an outer circumference, with an annular wall defined between the inner and the outer circumference. Plural holes are formed in the annular wall, so the petals of the body fit in the holes of the restricting ring to combine with the body. The inner surface of the inner circumference is sloped to restrict the movement of the constrictor. The constrictor has plural elastic petals, which have an inner clamp surface for closely clamping the surface of a plastic tube, and a pointed end for catching or loosening the plastic tube.
