摘要： PROBLEM TO BE SOLVED: To provide a coupling device for a pipe body for liquid, capable of confirming that the pipe body is inserted in its connection hole to a prescribed connection position without visual observation.
SOLUTION: A tubular engagement member 6 is fitted in an inner periphery of an intermediate diameter hole portion 21c constituting part of the connection hole 3. An engagement piece 6a which is inclined toward a radially inward direction from an inner peripheral surface of the engagement member 6 as it approximates the left is formed at a left edge surface of the engagement member 6. A taper-shaped guide surface 12g which elastically deforms the engagement piece 6a to a radially outward direction of the connection hole 3 with insertion of a secondary side pipe body 1 is formed at the top end portion outer peripheral surface of the secondary side pipe body (pipe body) 1. An engagement recessed portion 12d which faces the engagement piece 6a when the secondary side pipe body 1 reaches the prescribed connection position is formed at an outer peripheral surface of the secondary side pipe body 1 continuous to a right side of the guide surface 12g. The engagement piece 6 is returned and deformed by the elasticity of itself when it faces the engagement recessed portion 12d, and generates a hammering noise caused by colliding with a wall surface partitioning the engagement recessed portion 12d.
