A clamp that is a device connected to a flange for coupling a second pipe to a first pipe to prevent the second pipe from being separated is provided. The clamp includes a clamping body on which at least one pressing part protrudes from an inner circumferential surface thereof in at least one shape comprising a bottom edge of one of a cone shape, a truncated cone shape, a polygonal cone shape, and a faceted cone shape to press an outer circumferential surface of the second pipe. A cone of the pressing part has an apex oriented in a direction in which the second pipe is separated and a bottom surface facing a direction in which the second pipe is inserted so that the pressing part easily moves in the insertion direction and is difficult to move in the separation direction. According to the present invention, the slipping may be minimized regardless of the kind of steels to increase structural stability in the pipe fitting. |
