ABSTRACT:
A pipe fastening device including a split sleeve main tubular body with an upper and a lower internal tapered surface. A lower fixing member at the end of the pipe having a frusto-conically shaped body matching the lower tapered inner surface of the tubular body. An upper movable member also having a frusto-conically shaped body matching the upper inner tapered surface at the top of the tubular body. A bolt from an installation member passes through the fixing member and is fixed in the movable member so that tightening of the bolt draws the movable member toward the fixing member. The tapered surfaces cause the tubular body sleeve to expand for securing the tubular body in the pipe. The fixing member and the movable member have protuberant parts received in the groove of the split sleeve tubular body.
