PURPOSE:To accomplish stable connection with constant holding strength by arranging a collet cylindrical arm part, which is provided with a circular flange wall in its tip part, and is connected to a jaw wall, bringing the arm part, into contact with a resin tube outer circumferential face, and constructing the holding member slidably in the shaft center direction. CONSTITUTION:In a joint main body 1, a small diameter chamber 3'', an intermediate chamber 3', and a large diameter chamber 3 are formed around a cylindrical receiving member 22 to be fitted in the center part, of the joint main body 1, while the rear end circumference part of the large diameter chamber 3 is formed in a hanging wall 1'. A resin tube P to be connected is fitted around the cylindrical receiving member 22, and a circular elastic sealing member 4 is arranged between the outer circumferential face of the resin tube P and the intermediate chamber 3'. Facing the seal member 4, a holding member 5, which is provided with a circular flange wall 7 in the tip part of a collet cylindrical arm 6' having a slit 6 and a projecting wall 11 formed in the rear end part. and can be slid in the shaft center direction, is arranged, while a collar member 12 provided with an opening inclined face 14, which the projecting wall 11 of the holding member 5 is brought into contact with and is slid on, is fitted. |
