Summary:PURPOSE:To firmly close a hole of a pipe material such as smooth sheath without complicating a constitution. CONSTITUTION:A skirt 12b of a plug body 12 is inserted into an injection hole (hole) 20 of a smooth sheath (pipe material) 18 and by tuning a screw 14, a nut (flange piece) is moved axially inwardly so that the nut is drawn into a recess 34 of the skirt. And by an elastic expansion of the diameter of the skirt 12b which is caused by the movement of the nut 16, the hole 20 of the smooth sheath is closed.
