PROBLEM TO BE SOLVED: To provide a coupling structure for a mobile pipe in which connecting work between a fixing side pipe and a mobile side pipe is automatically carried out without requiring large man power, piping work is conducted by a small number of man-hours in uniform work time, management of work time is facilitated, work efficiency is improved, centering at a pipe connecting portion is facilitated, the occurrence of misalignment is avoided, and the reliability of the pipe connecting portion is also improved. SOLUTION: In this coupling structure for the mobile pipe, the fixing pipe 1 and the mobile pipe 29 attached to a moving element is detachably coupled with each other. The coupling structure for the mobile pipe comprises a coupling pipe 20 provided between the fixing pipe and the mobile pipe, a fastening member 14 provided between the coupling pipe and the fixing pipe, a piping cylinder 020 reciprocating the coupling pipe by working fluid pressure, and a fastening cylinder 8 reciprocating the fastening member by the working fluid pressure.
