A quick connector includes a body (4), a restricting ring (6) and a constrictor (7). The body has a central through hole (41) for liquid to flow through, a constrictor groove (42) in the central through hole for an O-shaped ring (43) and the constrictor (7) to fit therein, and plural petals (44) on an upper end. The restricting ring has a center hole (64), an inner circumference (60) and an outer circumference (61), with an annular wall defined between the inner and the outer circumference. Plural holes (63) are formed in the annular wall, so the petals (44) of the body fit in the holes of the restricting ring (6) to combine with the body. The inner surface of the inner circumference is sloped to restrict the movement of the constrictor. The constrictor (7) has plural elastic petals (70), which have an inner clamp surface (711) for closely clamping the surface of a plastic tube, and a pointed (710) end for catching or loosening the plastic tube.
