PROBLEM TO BE SOLVED: To enable a connection between a hose and a tube without leakage by axially pressing the hose on a tubular component fixed to a metal tube with cooperation of a nut screwed in the end portion of the rubber hose and a sleeve with a screw in order to expand the diameter of the hose and seal a space between the hose and the tube. SOLUTION: An unit composed of a tubular component 17 and a sleeve 18 is connected to a tube 15 with a nut 21 and a compression ring 22. A hose 16 is moved into the sleeve 18 while the sleeve 18 and a nut 20 are attached to the hose 16. The hose 16 is telescopically inserted in up to a small diameter part 23 of the tubular component 17 until the end portion thereof is engaged with a frustoconical middle portion 30. Then, a sleeve 19 is screwed into the sleeve 18 and abutted on the nut 20 so as to press the hose 16 on the frustoconical portion 30 of the tubular component 17, thereby expanding the diameter of the hose 16. Therefore, a space between the tube 15 and the tubular component 17 is sealed.
