Abstract

PURPOSE: To reliably secure a plug in a tubing by electric deformation by expanding the tubing by using a forming punch having two forming parts, before pressing the plug into the expanded part of the tubing by using one of said forming parts.
CONSTITUTION: A tubing 15 is expanded by using a forming punch 6 provided with the first forming part 61 having an outside diameter D1 which is smaller than the outside diameter of a plug 55 but larger than the inside diameter d2 of the tubing 15 and the second forming part 62 formed at the rear of the first forming part 61 and having an outside diameter D2 which is larger than the outside diameter of the plug 55. Then, the plug 55 is inserted into the end of the tubing 15 and pressed into a part 15a which has been expanded by the first forming part 61 and secured without damaging the inner surface of a part 15b which has been expanded by the second forming part 62 by the plug 55.
