A connection device for sealingly connecting tubular elements.

摘要

A device for connecting tubular elements (2), especially tubular casing elements of pipe-lines, is constituted by a sleeve (12), consisting of two end units (14) and an intermediate element (16). The end units (14) are adapted to be connected with the outer surface of either of two tubular elements which are to be connected with each other. Preferably the intermediate element (16) comprises a heat-insulating material (30). Each end unit (14) comprises an outer casing having a space which is open towards the adjacent tubular element. In this space there is positioned a sealing collar (20) which is sealingly compressible against the outer surface of the adjacent tubular element.
