A process for producing force-locking connections between tubular member inserted into each other or for attaching elements slid onto tubular members, by permanent radial expansion of several sleeves slid into these in a coaxial arrangement, in the case of which the sleeves are filled with a pressurized fluid and that pistons are inserted into the apertures of the, the with apertures of adjoining sleeves facing each other being closed by one single piston, and by bringing the two pistons closing the outwardly facing apertures of the outer sleeves closer together, the internal pressure is increased. |
