A connector for a branch pipe of a sewer pipe is provided to prevent separation caused by vibration by fixing a pressure ring, a fixing ring and a fastening nut strongly, to prevent the leakage of water on a connection by keeping watertightness using a packing, and to make construction simple and to shorten a period of construction by installing with simple progresses of perforating a sewer pipe, inputting a connector and coupling with a fastening nut. A connector for a branch pipe(130) of a sewer pipe contains: a cylindrical fixing ring(10) having an incline(12) formed on the outside of a cylindrical body(11), a screw thread(13) formed on the body and a through-hole(14) formed inward; a pressure ring(20) inserted to the outside of the fixing ring having a hanging projection(22) formed on one side of a body(21), a through hole(23) formed inward to insert the body of the cylindrical fixing ring and many cut grooves formed on the body longitudinally; a packing(30) coupled to increase watertightness; and a fastening nut(40) coupled to the screw thread of the fixing ring from the outside of the pressure ring. |
