PCT No. PCT/SE95/01001 Sec. 371 Date Mar. 5, 1997 Sec. 102(e) Date Mar. 5, 1997 PCT Filed Sep. 7, 1995 PCT Pub. No. WO96/07848 PCT Pub. Date Mar. 14, 1996A device for coupling two pipe sections comprises a clamping band of U-shaped cross-section with two inwardly directed flanges for encompassing end beads of the pipe sections which are to be coupled. The ends of the clamping band have cylindrical pockets each accommodating a cylindrical element which is rotatable about its own axis in the pocket. The clamping band is clamped by means of a threaded screw which is passed through an unthreaded hole in one cylindrical element and unthreaded holes in the ends of the clamping band, whereupon the screw is in threaded engagement with the other cylindrical element. |
