<P>PROBLEM TO BE SOLVED: To provide a quick connector for resin tube connection capable of effectively improving drawing strength of a resin tube, and capable of improving sealability. <P>SOLUTION: The quick connector 16 has a press-in fixing part 26 into the resin tube, and an insertion part 24 to be axially inserted by a counterpart pipe. An annular biting part 28-1 in a front side position is annular. In a position adjacent to a rear side, a maximum outer diameter is larger than an inner diameter of the resin tube 10 and smaller than the annular biting part 28-1 in the front side, an outer circumference face of a largest diameter part comprises a flat face 52 in an axial direction throughout a whole circumference, and an annular pressure contact part 50 is provided for fitting the flat face 52 in a pressure contact state throughout a whole circumference of an inner face of the resin tube 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
