Abstract

The device comprises a pair of sealing and support elements with external profile of a truncated cone, radially compressible and able to be fitted onto the end of one T1 of the pipes being joined, one being placed next to the other at the corresponding larger cross sections SM-SM'; a pair of wedge-shaped collars 15-15' that can be fitted onto the respective sealing and support elements 11-11' and each one having an internal conical surface SCI-SCI' able to co-operate in forced contact engagement with the outer conical surface SEE- SEE' of the corresponding sealing and support element and an external conical surface SCE-SCE' able to engage the corresponding internal conical surface SAI-SAI' of a reaction ring 16; a pair of hollow and deformable toroidal rings 19-19', acting axially on the wedge-shaped collars 15-15' and reacting at corresponding stops 17-17' of the reaction ring 16, which, by virtue of the pressure of a hydraulic fluid fed into their cavity, axially force the wedge-shaped collars between the respective sealing and support element 11-11' and the reaction ring 16 so as to irreversibly lock the joint. <IMAGE>
