<P>PROBLEM TO BE SOLVED: To easily discriminate the state of damage of the end side outer peripheral surface of a hose body caused by attachment/detachment to/from a pipe joint. Ž<P>SOLUTION: In a beer hose 10, the outer peripheral surface on one axial end side (a connection part 50A) of a hose body 50 is coated with a fragile film 52. When a locking claw 44 provided at the pipe joint 12 comes in sliding contact with the outer peripheral surface of the connection part 50A in attaching/detaching the hose body 50 to/from the pipe joint 12, the fragile film 52 is damaged. Since the fragile film 52 is different in color from the outer peripheral surface of the connection part 50A, the damaged state of the outer peripheral surface of the connection part 50A can be easily visually discriminated based on the damaged state of the fragile film 52.
