PURPOSE: To obviate the work of position-aligning a screw by providing a notch or a protrusion, stopped to a protrusion or a notch of a band, in a protrusive streak while the protrusion or the notch in the band.

CONSTITUTION: Protrusive streaks 11, 12 are formed in an end part of a hose 1 connected to an air cleaner 3 to provide a groove part 13 between the protrusive streaks. A protrusion 15 of height equal to the protrusive streak 11 is protruded toward the groove part 13 from a side surface of the protrusive streak 11. In a band 21 of a clamp 2, a notch 25, which stops the protrusion 15, is provided in an end part connected to a supporting cylinder 23. Since the protrusion 15 is stopped to the notch 25, during conveyance of the clamp- provided hose, the clamp 2 is prevented from moving in a peripheral direction in the groove part 13. Accordingly, when the hose is mounted to the air cleaner 3, a screw 22 is arranged in a predetermined position to obviate the position- aligning work as in the past.
