A pipe plug comprising a main body member 8 with a tapered portion 10, an elastomeric sealing ring 16 mounted on the taper and a locking member 18 connected to the main body by a coaxial threaded stud 20, the locking member preferably having a castellated circumferential flange with locking segments in the apertures of the castellations. When the plug is tightened in the pipe under pressure, the flange 32 urges the ring 16 into the gap between the taper and the pipe to seal the pipe, and the locking segments are forced outwardly to engage the internal surface of the pipe and lock the plug into position. <IMAGE> |
