Abstract
A connecting structure of a flexible tube with a mouthpiece, serving as elements of a treatment tool for an endoscope, includes at least one claw projection provided on an outer peripheral surface of a cylindrical connecting portion of the mouthpiece; and at least one claw-projection gap provided at a discontinuous portion of each claw projection. A connecting end of the flexible tube is inserted onto the cylindrical connecting portion so that at least one claw projection digs into an inner peripheral surface of the connecting end of the flexible tube. Each claw projection is provided perpendicular to the axis of the cylindrical connecting portion. A surface of each claw projection is inclined inward, toward the outer peripheral surface of the cylindrical connecting portion, in a direction so as to allow the cylindrical connecting portion to be inserted into the connecting end of the flexible tube.
