As is well known, in home appliances equipped with a water supply device or a pump used in industrial sites, etc., there are various connection devices that allow the fluid to easily branch on the fluid pipe, aerate, or extend the pipe length of the water. .

In this connection device, in order to prevent the fluid from being branched or amalgamated, or from being watertight or separated from the extended connection part, a large coupling force should be provided compared to the pressure exerted by the fluid on the pipe. This large coupling force makes the connection device It can be a big inconvenience when performing maintenance or separating the hose of the pipeline.

In addition, there is a fear that a plurality of pipeline hoses connected to the connecting device may be twisted with each other, and the pipeline hoses may be damaged by applying pressure to each of the pipeline hoses.
