The present invention relates to a branch pipe direct branching branch of the water pipe which is convenient to join the branch to the main water pipe and to form a branch pipe tightening coupling portion on one side of the branch to directly tighten the branch pipe. Specifically, both sides and the rear side are formed in a "U" shape, the inner side is formed as a device groove, the back side has a pressurized surface which is a semi-circular groove on the front side, and the back side has a pressurized surface formed with a tightening screw around the outer circumference. The main water pipe coupling part for adjusting the pressing force by inserting the operation tool having a screw and screwing the pressure cap having the tightening female screw to the inner diameter at the rear of the operating screw with the tightening screw of the branch body. Protruding on the other side of the device groove of the branching body and having a male thread on the outer circumference, the packing and the pressure port are put into the inner side of the coupling hole having a water hole communicating with the working groove in the inner center, and a taper hole is formed on one side of the inner diameter and the female screw on the other side. The outer circumference is formed as an inclined protrusion on the inner side of the tightening cap formed therein, the inner circumference has an annular protrusion and the outer circumferential wall is cut in the longitudinal direction, and a fastener having a cutting groove is introduced into the inner side of the tightening cap, and the tightening cap is screwed with the coupling hole. Branch pipe joints: Consisting of the main water pipe (7) into the device groove 11 and the operating port (2) from the rear side of the main water pipe (7) into the inside of the device groove (11), the guide projections (23) Is inserted into the guide groove 12 so that the actuating tool 2 slides forward and backward without departing from the inside o
