Claim 2:
3. The quick connector according to claim 2, wherein the tapered surface is inclined with respect to the prescribed direction in which the retainer moves and is also inclined in a direction in which the first leg part expands,
when the pipe is inserted into the connector main body,
the retainer moves in the prescribed direction from the standard position by applying a force in the prescribed direction on the tapered surface due to the pressing force on the tapered surface in the axial direction of the pipe by the annular protrusion, and the first leg part comes into contact with the first guide and is expanded and deformed by the retainer moving from the standard position in the prescribed direction,
the first leg part is expanded and deformed by applying a force on the tapered surface in an expansion direction of the first leg part due to the pressing force on the tapered surface in the axial direction of the pipe by the annular protrusion, and
the annular protrusion of the pipe is allowed to pass through the first leg part in the insertion direction by expansion and deformation of the first leg part.
