[ We claim:] [1.] A device for coupling first and second pipe sections, each pipe section having an outwardly directed end bead at a respective end thereof, each end bead having a radially outwardly directed surface and an end surface opposing the other end bead when the first and second pipe sections are coupled in an end-to-end relationship, said device comprising:an annular clamping strap having two opposite, spaced-apart end portions, the clamping strap being of substantially U-shaped cross-section and comprising:an annular bead bridging member having a radially inwardly facing inside surface extending linearly across the radially outwardly directed surfaces of the end beads when arranged in the end-to-end relationship, andtwo flanges extending inwardly from opposite edges of the bead bridging member, the bead bridging member and the two flanges arranged for securely encompassing the end beads;a clamping mechanism arranged in connection with the end portions of the clamping strap and adapted to tighten the clamping strap around the end beads of the pipes;an inner circumferential seal disposed on the inside surface of the bead bridging member of the clamping band to abut against the radially outwardly directed surfaces of the end beads and configured to fill a space between the radially outwardly directed surfaces of the end beads and the inside surface of the bead bridging member without extending into a space between the opposed surfaces of the end beads when coupled in the end-to-end relationship; anda sealing element arranged between the end portions of the clamping strap for connection thereto and for sealing a joint between the end portions when tightening the clamping strap, the sealing element separate from the inner circumferential seal and configured to press against the inner circumferential seal when the clamping strap is tightened around the end beads of the first and second pipe sections, whereby the sealing element and the inner circumferential seal are cooperative to seal a region between the first and second pipe sections.
