A pipe plug is disclosed which includes a disc-like screw plate, an elastic sealing ring, a horn-like pressure block, and a lifting eye. The screw plate receives the bottom edge of the sealing ring and the horn-like pressure block is mounted on the upper edge. The screw plate has a central rod that extends upwardly through a hole in the pressure block. The lifting eye is then threadedly received on the end of the rod and as the lifting eye is turned, the block and plate will be urged together causing the sealing ring to expand against the internal wall of a pipe.
