PROBLEM TO BE SOLVED: To efficiently and easily perform installation work of an inline work machine to a socket pipe part by using a constitution therefor, by efficiently and easily performing fitting-connecting work of an insertion port pipe part to the socket pipe part. SOLUTION: The socket pipe part 6 forms an attaching-detaching recessed part 29A for allowing the extraction-insertion movement in the pipe axis direction of a locking part 26 of the insertion port pipe part 11, and a slipping-out preventive wall part 29B for checking the slipping-out movement by abutting on the locking part 26 when rotating the locking part 26 of the insertion port pipe part 11 inserted via this part to a predetermined installation position. The socket pipe part 6 forms a connecting flange part 7B to be joined by a flange with the inline work machine C sendable into the socket pipe part 6 in the other end part of a joint pipe 7 fitted around and connected to the socket pipe part 6. A fitting pipe part 7A of the joint pipe 7 is provided with a rotation regulating part 40 for checking relative rotation of both by engaging with the attaching-detaching recessed part 29A of the socket pipe part 6, and a fixing means 41 for fixing slipping-out to the socket pipe part 6 while maintaining an engaging state of these parts.
