Claims

[Claims for Utility Model Registration] 1. A piping joint device comprising a female joint member and a male joint member that fits into the female joint member, the female joint member having a flange portion,
forming a mouth edge extending forward from the outer periphery of the flange portion and bending inward, and forming an inner diameter of the flange portion to be slightly smaller than a diameter of the mouth edge;
The male joint member includes a large-diameter holding part that holds the annular lock spring in a state in which the diameter is larger than the diameter of the mouth edge, and a stopper having a larger diameter than the large-diameter holding part at the tip of the large-diameter holding part. in the male joint member, the lock spring is held in a reduced diameter state having a diameter larger than the inner diameter of the flange part and smaller than the diameter of the mouth edge part at the forward part of the stopper part of the male joint member. A pipe joint device characterized in that a small diameter holding portion is formed to be continuous with the stopper portion. 2. The pipe joint device according to claim 1, wherein the large-diameter holding portion of the male joint member is configured to be separable from the stopper portion. 3. The male joint member is composed of an annular member in which the small-diameter holding part and the stopper part are formed, and a nut member in which the large-diameter holding part is formed at the tip, and a sleeve is integrally disposed in the caudal direction from the annular member. 3. The pipe joint device according to claim 2, wherein the nut member is screwed into the sleeve. 4. The sleeve is formed in such a length that when the nut member is tightened into the annular member, a tail end portion of the sleeve protrudes rearwardly of the nut member, and a tool engagement is provided at the tail end of the sleeve. A pipe joint device characterized by forming a joint. 5 The threaded portion of the nut member is a tapered thread,
A slit extending in the axial direction is formed in the sleeve, and a protrusion is integrally provided on the inner periphery of the sleeve to engage with an engagement groove formed on the outer periphery of the piping member to which the annular member is attached. The pipe joint device according to claim 3 or 4.
