Claims (1)

[Claims for Utility Model Registration] (1) The body has a number of fluid passages corresponding to the fluid passages of the multi-pipe, the fluid passages are open at one end, and the inner wall thereof has a step. A tube insertion hole is formed, and multiple tubes mutually fixed by connecting members are inserted into the tube insertion hole to connect to the fluid passage of the body, and a stepped portion of the tube insertion hole is formed inside the tube insertion hole. and a bulging portion of the multiple tube formed by the protrusion of the connecting member, and a locking member is attached thereto to prevent insertion and removal of the multiple tube. (2) In the connector described in claim 1 of the utility model registration claim, the connecting member is formed into a double tube shape consisting of an outer tube body and an inner tube body separated by a predetermined distance from each other via a stay, and the inner tube body A multi-pipe connector comprising a sharp annular protrusion formed on the inner circumferential wall of the outer tube body, and an annular protrusion having a semicircular cross section formed on the outer circumferential wall of the outer tube body. (3) Scope of claims for utility model registration, paragraph 1 or 2
In the connector described in paragraph 1, the locking member includes a ring-shaped base, a flange is formed at the upper end of the base, a plurality of slits are formed on the circumferential surface of the base, and the lower end of the base is formed with a flange. A multi-tube connector in which a stepped portion of the tube insertion hole and a slanted surface that engages with the bulging portion of the tube body are formed in the portion.
