<p>PROBLEM TO BE SOLVED: To attain firm tightening of a synthetic resin pipe by providing a tongue piece with a space apart in a peripheral direction in a side end face of a socket, and tightening the pipe with a band linked over each tongue piece, in a device heating a connection surface fused by heating with a current carried in an electric heating wire buried in the socket to fuse the synthetic resin pipe connected. SOLUTION: In right/left both side ends in a synthetic resin-made pipe joint 1 burying an electric heating wire in a socket, a small tongue piece 3 formed with a hole 2 for inserting a hose band in protrusively formed one by one, a hose band 4 is inserted to the hole 2 of each tongue piece 3 to be set. When the pipe joint 1 and a synthetic resin pipe 5 are fused, after the synthetic resin pipe 5 is inserted to both sides of the pipe joint 1, fastening by the hose band 4 is performed, so as to tighten the synthetic resin pipe 5. That is, by fastening the synthetic resin pipe 5 with the hose band 4, the synthetic resin pipe 5 is tightened by direct adhesion by the hose band 4 with the tongue piece 3, so as to realize stronger tightening.</p> |
