PROBLEM TO BE SOLVED: To provide a joint dispensing with secondary machining to dissolve unnaturalness in appearance, the joint permitting the assembly of a pipe structure using a partition wall body, while permitting the disassembly of the whole pipe structure and facilitating maintenance. SOLUTION: To joint resin coated steel pipes 5 having clamping ribs 4, this joint 1 is assembled by jointing a plurality of fitting cylinders 1a, 1b for insert-fitting cylindrical parts of the resin coated steel pipes 5, in an intersecting manner through a joint cylinder 1c connected to one end of at least one fitting cylinder at two adjacent fitting cylinders, and dividing the fitting cylinders 1a, 1b into a pair of segments 6, 7 and fastening them with a bolt 11 and a nut 12 at a part separating from a pair of clamping ribs 4. The divided edges on the internal angle side extending between two adjacent fitting cylinders are widened to a width allowing a pair of clamping ribs 4 to project, over the whole length, and covering parts 6e, 7e for covering the outer side faces of a pair of clamping ribs 4 along both sides of the whole length of a widened part are formed integrally with each segment.
