Claim 3:
4. The quick connector according to claim 1, wherein the tapered surface is inclined in a direction in which the first leg part expands,
when the pipe is inserted into the connector main body,
in a state in which the first leg part is not in contact with the first guide, 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.
