Therefore, in the connecting device of the above-mentioned embodiment, when the residual chlorine amount in the tap water flowing in the water pipe W is periodically measured by the sensor S as described above, the functional parts are frequently fed to the pressure piping. For applications that require attachment / detachment, the attachment / detachment can be simplified.

In the above, the connection device of the present invention is used to connect the water pipe W and the sensor S for measuring the amount of residual chlorine contained in the tap water flowing in the water pipe W. Although only examples have been described, the connection device of the present invention can be used for pressure pipes other than water pipes such as oil pipes and gas pipes. As functional parts, other than the above-mentioned sensor S for measuring the residual chlorine amount, for example, various conventionally known sensors for measuring the pressure in the pipe, the flow direction of the fluid, the flow rate, etc., and the inside of the pipe can be observed. There is an endoscope for doing so.

In addition, various design changes can be made without changing the gist of the present invention.
