Twisting of hose incident to clamping is perfectly prevented. A hose (H) is inserted along the outer peripheral surface (1b) of a nipple (1), a loose fitting portion (4) is rotatably fitted along the outer peripheral surface (1b) of the nipple (1), the loose fitting portion (4) and a sleeve (2) are s eparately fixed so as not to be movable in the axial direction, and a clampi ng member (3) is threaded on the outer peripheral surface of the loose fitti ng portion (4) so as to be movable in the axial direction toward the sleeve (2). Thus, when the clamping member (3) is drawn in the fastening direction by rotating only the loose fitting portion (4) without rotating the clamping member (3), the diameter of the sleeve (2) is reduced with no rotational fo rce acting on it. This causes the inner peripheral surface (H1) of the hose (H) to be in contact with the outer peripheral surface (1b) of the nipple (1 ) with the hose (H) free from any external force due to rotational friction.
