<P>PROBLEM TO BE SOLVED: To provide a locking device for a resin tube capable, which prevents the resin tube from being disconnected from a pipe body and simplifies connection work of the resin tube. <P>SOLUTION: The locking device 23 for the resin tube comprises a cylindrical retainer part 25 and a cylindrical support part 27, which are formed integrally with each other. The cylindrical support part 27 has a diameter larger than that of the cylindrical retainer part 25. A difference between the inner diameter of the cylindrical retainer part 25 and the outer diameter of the axially other side part 13 of the pipe body is set substantially equal to twice the thickness of the resin tube 37 in a fastening portion 33. Cuts 47 are formed in the cylindrical support part 27 and inner plate pieces defined by the cuts 47 are bent radially inwardly to form restricting press parts 43. <P>COPYRIGHT: (C)2008,JPO&INPIT |
