PROBLEM TO BE SOLVED: To provide a tube connecting structure of a treatment implement for an endoscope such that a flexible tube and a base member can be securely interconnected by means of a simple structure and through a simple operation, with no appreciable increase in outside diameter of their connection. SOLUTION: In the tube connecting structure of the treatment implement for the endoscope, an edged pawl-like projection 13 is provided to project from the outer peripheral surface of a cylinder portion 11a formed at the end of the base member 13, and the cylinder portion 11a is connected to the end of the flexible tube 2 by a press fit. The pawl-like projection 13 is circumferentially formed on a cross section perpendicular to the axis of the cylinder portion 11a, and the fitting surface of the pawl-like projection 13 which fits the flexible tube 2 is formed into an inclined surface inclined backward during the press fit. A portion 13a of the pawl-like projection 13 is partially cut.
