PROBLEM TO BE SOLVED: To easily attach/detach a hose 20, having a bellows part via a socket 50 in a hose connection structural body. SOLUTION: In this hose connection structural body, the hose 20, having the bellows part 22, is connected to a mounting block 24 via the socket 50. The mounting block 24 is provided with a block side engagement claw 25c, projected in the opening outer circumference end of a block body 25. The socket 50 is provided with a socket body 51 which is cut and divided by a slit 51a to be elastically expanded/shrunk in diameter, and a fixing engagement claw 51b is engaged with the block side engagement claw 25c. For removing the socket 50 from the mounting block 24, a rotation directional force is applied to a pressing operation part 51c for expanding the socket body 51 in diameter, and consequently, the fixing engagement claw 51b is released from the block side engagement claw 25c.
