Abstract: PURPOSE: To prevent the occurrence of leakage of fluid and dislocation of a joint even during a use for a long time by a method wherein the first lock part of an insertion part and the second lock part of a support part are fastened against each other by a coupling fixing member. CONSTITUTION: After coupling fixing members 31 and 32 are inserted in the support parts 3 and 23 of joints 1 and 21, a coupling joint is connected to the branch parts 4, 14, and 24 of joints 1, 11, and 21 and a closing plug to the insertion part 22 of the joints 21. The insertion part 2 of the joint 1 is inserted in the support part 23 of the joint 21, the insertion part 12 of the joint 11 in the support part 3 of the joint 1, and coupling fixing members 31 and 32 are temporarily locked. After a main pipe is connected to the support part 13 of the joint 11 and a branch pipe to the coupling joint of the branch parts 4, 14, and 24 of the joints 1, 11, and 21, the coupling fixing members 31 and 32 are firmly fastened and the joints 1, 11, and 21 are prevented from rotation.
