JOINING DEVICE BETWEEN TWO PIPES COMPRISING RETRACTABLE SUPPORTING PIECES

摘要

Joining means between two pipes, each provided with a collar having a given external diameter and able to compress a gasket between these two collars, said means having two flanges with aligned holes and an internal diameter smaller than the external diameter of the collars and tightening means traversing said holes making it possible to move the flanges together, whereby at least one of the flanges comprises an external cylindrical ring with an internal diameter larger than the external diameter of the collars and bearing parts disposed within said ring and in which are formed said holes, articulated on one lateral face of the ring, so as to be able to tilt into an overriding position in which the internal diameter of the flange substantially corresponds to the internal diameter of the ring.
