PURPOSE: A reinforcing element for a branch pipe having fitting parts is provided to prevent the deformation due to the winding load of the branch pipe and the slippage due to a speed difference between the branch pipe and the reinforcing element. CONSTITUTION: A reinforcing element for a branch pipe having fitting parts includes a cylindrical reinforcing part(20) to be inserted into an inner diameter of a branch pipe, a flange(40) formed at an end of the reinforcing part, and a plurality of first and second fitting parts(50,60) cut at a part of the flange and folded toward an end of the branch pipe, wherein the reinforcing part has an end retracted to be easily inserted into the inner diameter of the branch pipe and formed with a groove(30) along the periphery of the end, and the first and second fitting parts are respectively cut in the peripheral direction and the radial direction of the flange disposed alternately. |
