PROBLEM TO BE SOLVED: To provide a structure for making a worker's hand hardly touch a tip of a fixing screw at any of inner and outer spaces of a casing 10, with respect to the structure for mounting a pipe connection tool, having a mounting flange 4 overhanging a cylindrical body P, to a mounting hole 17A of the casing 10 by inserting an insertion-side end portion 31 of the cylindrical body P to the mounting hole 17A, and fixing the fixing screw into the insertion hole 16 of a screw around the mounting hole 17A from a fixing screw inserting portion 42 of the mounting flange 4 after the insertion. SOLUTION: A guard member 33 positioned in the direction of the insertion-side end portion 32 from the mounting flange 4 at an interval is integrally formed on the cylindrical body P, the guard member 33 can be inserted into the mounting hole 17A with the insertion-side end portion 31 of the cylindrical body P, and the guard member 33 and the fixing screw inserting portion 42 of the mounting flange 4 are opposed to the screw insertion hole 16 from front and rear sides after the insertion.
