Zusammenfassung:	PURPOSE: To prevent damage of tube and to strengthen the connection of tube and flange by inserting the flange for fixing a machine in a top part of a metal tube, and forming a projective bulge part and a pilot part for inserting. CONSTITUTION: The top part 1a of a metal tube 1 fixed in a hose has a smaller diameter, a flange 2 for fixing a machine is inserted in the top part 1a. Then, while the border part of the top part 1a and the main body of the tube is conically punched, a flange 2 is pressed into the tube main body. After that, the end surface of the top part 1a of the tube is axially pressed, radically projective bulge part 1b and a pilot part 1a' for being inserted into a hose are formed in the top part 1a. As a result, the flange and the tube main body are securely connected and moreover the damages of the surface of the pilot part is prevented.
