<p>PROBLEM TO BE SOLVED: To provide a quick connector (1) which has a retainer (30) having a checker function, and can prevent a pipe body (3) from being easily pulled out even immediately after the pipe body (3) is inserted.SOLUTION: A pair of leg parts (32, 32) of a retainer (30) each include a temporary pull-out preventing part (41), a confirming claw (42), and a main pull-out preventing part (43). When the retainer (30) is positioned in an initial position, the pair of the leg parts (32, 32) are opened in accordance with abutting of the temporary pull-out preventing part (41) to an annular protrusion (3a) of a pipe body (3), and thereby, the pipe body (3) can be inserted, and the temporary pull-out preventing part (41) is locked to the annular protrusion (3a) by reduction of an opening amount, and thereby, the pipe body (3) is prevented from being pulled out. The main pull-out preventing part (43) is locked to the annular protrusion (3a) so as to prevent pull-out of the pipe body (3) when the retainer (30) is positioned in a confirmation position.</p> |
