Abstract
A coupling for connecting a connecting pipe to a main pipe. The coupling comprises a coupling member and a nut screwed into the coupling member. A projection having an arc-shaped cross-section and extending in the circumferential direction of the outer wall of the main pipe is formed on the outer wall of the main pipe, and the coupling member is rotatably fitted onto the projection. A conical shape groove connected to the high pressure fluid passage in the main pipe is formed on the outer wall of the main pipe, and the tip portion of the connecting pipe is pressed against the conical shape groove by tightening down the nut.
