The insert member is inserted inside a pipe connection part(111) of the ferrule. The insert member is inserted in the leading end of a PE pipe(160). The packing member and pressing member are successively axis-connected in the exterior of the PE pipe in which the insert member is inserted. The cap member is spirally combined to an external side of the pipe connecting unit from the rear side of the pressing member. The pressing member and packing member are successively pressurized to the combining direction of the cap member in order to fix the packing member between the outer side of the PE pipe and the inner side of the pipe connection part. |
