The present invention relates to a clamp for fixating a coupling unit of a coupled pipe. The clamp for a pipe according to the present invention comprises: a main body including a first main body where a link is hinged to the upper part thereof, a fastening protrusion is formed on the lower part thereof, an inserting hole is formed on the fastening protrusion, and a spiral hole is formed on one side of the inserting hole, and a second main body where the link is hinged to the upper part thereof, and a fastening screw is hinged to the lower part thereof; a link which is hinged to the upper part of the first main body and the second main body; a fastening screw which is coupled to the lower part of the second main body; a fastening bar where a nut is formed on one side thereof, a spiral line is formed on the outer side thereof, and a spiral hole is formed on the inner side thereof; and a hinge pin which hinges the fastening screw and the link at the main body in order to rotate. Therefore, the clamp can be fixated to a joint of pipes with various sizes by forming the link, for connecting a pair of clamp main bodies, in order to be folded, and can prevent the loosening of the clamp coupled to the joint of the pipe due to external impacts by forming the spiral line on the fastening protrusion and coupling the fastening bar with a spiral line to the above spiral line. |
