PROBLEM TO BE SOLVED: To provide a compression tool capable of solving a point at issue of a conventional compression tool and fastening works of a plurality of sizes without exchanging a work holding member (holder) and simple in operation. SOLUTION: This compression tool for a tube fitting constitutes its characteristic feature of using a torsion coil spring as a tool to compress the tube fitting by holding it in the axial direction and a mechanism to energize a plurality of pipes and the tube fittings to apply to in such a way to clamp them against their sizes (outer diameters) of the pipes and tube fittings on outer peripheries of the pipes and the tube fittings by holder parts A and B having semi-circular arc shape parts.
