Abstract

See full text

A pipe-connecting device includes: an inner ring having an outer circumferential portion having, at a tip end, a tip-contracted outer-circumferential flared surface that flares a tube end portion; a pipe joint body that has a tubular screwing portion having an external thread; and a union nut having an internal thread. The inner ring flares the tube end portion, and is inserted into the tubular screwing portion. The tip-contracted outer-circumferential flared surface is clamped and pressed through the tube by the union nut which is screw-advanced by screwing with the tubular screwing portion. A tube pressing portion which is in the union nut, and which presses the tube against the tip-contracted outer-circumferential flared surface is formed into an inclined inner circumferential surface which is inclined in the same direction as the outer-circumferential flared surface with respect to the axis of the tubular screwing portion.
