PROBLEM TO BE SOLVED: To secure the airtightness and fluid-tightness of a synthetic resin pipe connected to connected body by inserting and fitting a sleeve to the inner side of the connecting end of the synthetic resin pipe, and also mounting a spiral coil member on the outer side of the connecting end, then mounting a compression member on the outer side of this coil member. ;SOLUTION: One end side of a sleeve 10 is inserted to a connected body A, and an O-ring 40 is mounted between the connected body A and the sleeve 10. Tow pin holes 51 are formed in the connected body A, locking pins 50 are inserted to these pin holes 51 and locked to the grooves 12 of the sleeve 10, thereby the sleeve 10 is prevented from being slipped off. Coil members 20 are mounted on the outer side of a synthetic resin pipe B, and a compression member 30 is mounted on the outer side of this coil member 20. Member by which the diameters of the coil members 20 are shrunk, are employed as the compression member 30, therefore the diameters of the coil members 20 are shrunk by the compression of this compression member 30 so as to tighten the synthetic resin pipe B, and the sleeve 10 and the synthetic resin pipe B are strongly and airtightly or fluid-tightly connected to each other.;COPYRIGHT: (C)1997,JPO
