ABSTRACT:
A quick connector comprises a tubular-shaped female member, a tubular-shaped male member, and an engager member which comprises a "C" ring-shaped and tapered stopper whose diameter can be increased in said annular-shaped concave, and which has the smaller diameter ends having the small diameter at the inner side of said female member and having the large diameter at the side of said opened flange to engage said engager projection, and which has the larger diameter ends having the diameter larger than that of said opened flange of said female member to face the inside end surface of said opened flange; a regulator which is installed in the axial direction to said stopper, and which is projected in the centrifugal directions than do the larger diameter ends of said stopper, and which is brought into contact with the inner peripheral surface of said annular-shaped concave to regulate the displacement in the radial direction of said stopper; and a linkage for connecting said stopper and said regulator. In the quick connector, the smooth insertion of the male member and the satisfactory diameter enlargement of the stopper can be obtained.
