The present invention relates to a pipe connecting device, comprising: a socket pipe with a flange protruding from the edge of each step; a packing ring coming in contact with the flange; and a clamp with the structure of a circular arc divided from a ring shape into two or more parts. The clamp has a combining unit vertically protruding from each step of a circular arc on the front surface and a bolt hole punched. In the two or more combining units coming in contact with each other when clamps are combined in a ring shape, a female fastening ring and a male fastening ring are respectively formed on each of the other pairs of combining units excluding a pair of combining units. The female fastening ring protrudes in an ′L′ shape on the front surface toward the combining unit in contact with the sides of the thickness of the combining units, and the male fastening ring protrudes in a ′T′ shape on a side surface from the center of the thickness of the combining units. The male fastening ring can hang on between the female fastening rings protruding from the sides of the thickness of the combining units. After wrapping around the flange and the packing ring, into which a pipe to be connected is inserted, in a status of a hinge with a female fastening ring of a clamp having a male fastening ring of another clamp hung on, they are able to be combined with a bolt through a bolt hole in the combining units in contact with each other for easy combination of clamps. |
