Claims

[Scope of Claim for Utility Model Registration] (1) A pipe with a flow hole penetrating through the shaft core, and a cylindrical wall connecting to the metal pipe on the tip side, and a connecting gap with the hose on the rear end side. In the joint body which is held and has an inner mantle wall and an outer mantle wall in an overlapping manner, the outer circumference of the connecting cylinder wall 3 is a threaded surface 7, and a mating metal is provided on the front surface of the tip of the connecting cylinder wall. A coupling joint for connecting a small diameter metal pipe and a hose, characterized in that it has a seat surface 8 that abuts and engages a connecting portion provided at the end of the pipe P. (2) Claim 1 of the Utility Model Registration Claim states that the seat surface 8 is formed into a tapered conical surface 9 that abuts and engages a flared wall P' provided at the end of the mating metal tube P. A unique joint that connects a small diameter metal pipe and a hose. (3) In the scope of claim 1 of the utility model registration claim, the seat surface 8 is formed into a concave conical surface 10 that abuts and engages a spool wall P'' provided at the end of the mating metal pipe P. A joint that connects a small diameter metal pipe and a hose.
