装置をコンパクトにできないという問題があった。[Problems to be solved by the invention] When connecting the ends of pipe lines of piping systems such as water supply and drainage pipes, generally the pipe ends are internally and externally screwed together or connected using pipe joints such as flange joints and union joints. However, in both cases, the work is complicated because the pipe or the joint member is rotated and screwed and fastened, and a space for rotating work is required around the connection part, especially in the electrolytic ion water generator. In addition, it is difficult to connect at places where many piping systems such as water supply and drainage and cleaning liquid gather in small places on both sides of the electrolytic cell,
There is a problem that the device cannot be made compact.
本考案はこの問題を解決するためになされたもので、構

に節度感をもって嵌合する。According to the above structure, when the fastener of the present invention is inserted through the U-shaped frame opening from any lateral direction of the pair of axially abutting pipe end flanges, the two locking sides are provided so as to face each other. The tip of the piece slides against the outer peripheral surface inside the flange, and the resilient frame is opened against the spring force. When pushing the rear part of the U-shaped frame and inserting the fastener deeper, the arc-shaped edge piece of the locking side piece fits with a click sound along with the snapping sound on the outer peripheral surface inside the flange with elasticity given by the resilient frame. To do.
