ABSTRACT:
A coupling for establishing a fluid-tight connection between adjacent open ends of substantially coaxial hollow elements, especially pipes, includes a pair of flanges, each formed from a section of a profiled strand, respectively fitted about the outer surfaces of the elements and provided with contact surfaces arranged to fit upon each other upon axial movement of the flanges toward each other, and in which at least one of the flanges is provided with an annular cutout forming with the other flange and the outer surfaces of the elements at the adjacent ends of the latter an annular space. A compressible or ductile sealing element is located in this annular space, and a device engaging the flanges is constructed to move the latter in axial direction toward each other.
