<p>PROBLEM TO BE SOLVED: To eliminate an other joint, a stopper member and a releasing member of a connecting portion to thereby simplify an interior-furnishing structure, by interior furnishing a collet member such that it can be freely moved in an axial direction and by pressing a claw wall inward and biting in it in the outer peripheral surface of a resin tube by butting it into contact with the slant wall of the connecting portion. SOLUTION: In a connecting portion 1, and collet member 4 having a cylindrical base part 4''' connecting to an elastic slit wall 4a which has an inward claw wall 4' at the tip end and a projecting wall 4'' made on the outer periphery side thereof and elastic sealing members 3 on the inner and outer peripheral surfaces of the base part 4''' is interior furnished such that it can be freely moved in the axial direction. After a resin tube P' fitted on an inserting member 2 is inserted into a room 1' with an enlarged diameter, or after a resin tube P' is fitted on the outer peripheral surface of an inserting member previously inserted, if the resin tube P' is slightly pulled backward, the collet member 4 follows the pulled-back resin tube P' to put the projecting wall 4'' into contact with the slant wall 1'', whereby the claw wall 4' is passed and bit in the outer peripheral surface of the resin tube P', which connects a metal pipe P to the resin tube P'.</p> |
