PROBLEM TO BE SOLVED: To provide a piping connection part for endoscope which makes a piping tube fixed to a piping pipe hard to loosen regardless of addition of vibration, impact or the like, and enables a good connection state to be maintained without leakage for a long period.
SOLUTION: In the outer peripheral part of an inner cylinder 3 and the inner peripheral part of an outer cylinder 4, the inner cylinder 3 is elastically transformed by the outer cylinder 4 sliding from back of a piping tube 2 toward the distal end, and when its sliding action is released, the outer cylinder 4 is pushed back by repulsive force of the inner cylinder 3, so that abutment parts (38 and 42, 39 and 43) are formed which act to press the inner cylinder 3 to a bulge 21 of the piping tube 2.
