PROBLEM TO BE SOLVED: To provide a tubular treatment tool for an endoscope which can be produced at a low cost by minimizing the number of parts so as to facilitate assembling. SOLUTION: Diameter expansion end parts 10a and 11a expanding like funnels or flanges are formed respectively at the base end of a sheath tube 10 and that of a folding preventing tube 11. The parts 10a and 11a of the tube 10 and those of the tube 11 are overlapped and the overlapped part is inserted and fixed tightly between a pressurizing and fixing member 30 to be engaged with a hand-side metallic cap 20 and the cap 20. |
