Abstract

The device comprises a body preferably ring-shaped the outer surface of which bears a number of radially oriented assemblies which can expand from a retracted position. The sides of the body bear supports which align the axis of the ring with that of a tubes placed end-to-end. Two sleeve can be rectified for assembly to be used in pipes for conveying pressureised fluids.
