PROBLEM TO BE SOLVED: To provide a joining metal fitting which prevents the reduction of a connection force even if pressurization and stop of pressurization are repeated many times. SOLUTION: In this joining metal fitting 1, an engaging claw 3 is inclined at an inclination angle of 1 to 5 degrees for the vertical direction in the reverse direction to the direction of turn when engaging so that a pressure is applied in the direction in which a joining annular body part 2 and the engaging claw 3 leave from each other when water passes and the engaging claw 3 is deformed in the vertical direction. However, even if pressurization and stop of pressurization are repeated, it is possible to maintain an engaging force of the engaging claw 3 and the joining annular body part 2 when pressurization stops at a large value.
