PROBLEM TO BE SOLVED: To maintain the clamped state of a hose over a long period of time without shearing stress being applied to an elastic body. SOLUTION: The annular elastic body 4 compressively deformed in a radial direction with the diameter reduction of an expansion sleeve 2 is provided between the inner peripheral surface 2a of the expansion sleeve 2 and the outer peripheral surface H2 of the hose H. The expansion sleeve 2 is arranged so that the outer peripheral surface H2 of the hose H is pressed toward the outer peripheral surface 1a of a nipple 1 by the resilience of the elastic body 4. Consequently, even if the resilience of the hose H itself decreases and the hose becomes thin-walled due to prolonged use or the like, the inner peripheral surface 4a is projected by the resilience of the elastic body 4 in association with it, and the inner peripheral surface H1 of the hose H comes in close contact with the outer peripheral surface 1a of the nipple 1 to always maintain the clamped state of the hose H.
