A coupler for the pipe is provided to minimize the manpower using the pipe coupling by coupling a first pipe and a second pipe with the simple operation of rotating the joint. A coupler for the pipe comprises the spacer(10) of the tubular covering the outer circumference of the end part of first and second pipe; the first and second sealing members (20,30) adhering closely to both side end point of spacer; the first screw part(41) includes the first body(40) having first taper and the inside diameter which becomes smaller; the second body(50) including the annular projection and the second taper(52) formed in the part facing to the first screw part; the first fix ring(60) of the cut annular shape preventing the thing in which the first pipe is broken away from of the first body; the second fixing ring(70) having the cut annular form preventing the thing in which the second pipe is broken away from the second body; and the joint(80) has the annular holder setting up the annular projection of the second body screwed in the first screw part and the second screw part, and adhered the first and the second body closely.
