Claims

[Claims for Utility Model Registration] (1) A joint body, a bag-shaped nut screwed into the joint body, and a bag-shaped nut located between the joint body and the bag-shaped nut that is deformed by the tightening force of the screwing operation. In a piping joint comprising a sleeve that bites into a pipe and restricts the pipe from coming out, an inner nut is provided between the joint body and the sleeve, the inner nut being threadedly engaged with the joint body and having an outer diameter smaller than the inner diameter of the bag-shaped nut. When installing the above pipe, the sleeve is deformed by the tightening force of the screwing action of the bag nut when the inner nut is screwed into the fitting body, and it bites between the pipe and the fitting body, and when the above pipe is removed, the inner nut is screwed into the fitting body. A piping joint characterized in that the sleeve is removed together with an inner nut by abutting a part of the sleeve. (2) A joint body, a bag-shaped nut screwed into the joint body, and a nut located between the joint body and the bag-shaped nut, which is deformed by the tightening force of the screwing operation and bites into the pipe to prevent the pipe from coming out. A piping joint comprising a regulating sleeve, wherein an inner ring is provided between the joint body and the sleeve and has an outer diameter smaller than the inner diameter of the bag nut, and the bag nut and the inner ring have an inner ring. A tubular hole is bored, and the tubular nut and the inner ring are connected by a connecting member of the tubular nut and the inner ring that is attached to the tubular hole, and the inner ring is detachably attached to the joint body. A guide section is provided for installation, and when the pipe is installed, the inner ring is installed on the fitting body, and then the bag-shaped nut is screwed on.The tightening force deforms the sleeve and bites into the pipe, and when the pipe is removed, the sleeve is shaped like a bag-shaped nut. A piping joint characterized in that an inner ring moves in conjunction with the nut removal operation and comes into contact with a part of the sleeve so that the bag-shaped nut, the inner ring, and the sleeve can be removed at the same time.
