A horizontal female screw(12) is formed on the inner circumference of the recessed groove. A horizontal male screw(22) is formed on the outer circumference of the front end of a pipe(20). A vertical protruded rim(21) is formed outside the recessed groove. The male screws of pipes are inserted to the inner circumference of the recessed groove.
