A water purification pipe through which purified water (hereinafter, referred to as purified water) passes is connected, raw water supplied from the raw water pipe is purified through the purification member, and purified water is discharged through the water purification pipe. A water purifier having a structure for sending to a water faucet is generally widely used. The water purifier of the type described above purifies raw water through a purifying member such as activated carbon or a hollow fiber membrane, so that when used for a long period of time, the purification capacity is reduced due to a decrease in activated carbon adsorption power and clogging of the hollow fiber membrane. Therefore, it is necessary to replace the purifying member inside the housing or the water purifier itself in an appropriate cycle, and the water purifier and the raw water pipe and the water purifier are configured to be detachable for this replacement work. In order to facilitate the replacement work of the above-mentioned water purifier, it is known that the raw water pipe and the inlet of the water purifier, and the outlet of the water purifier and the water purifier are connected by one-touch joints, respectively.
