ABSTRACT:
The invention relates to a device for connecting flanged pipes. For this purpose, a multiple-section clamp is mainly used which includes inwardly protruding flanges engaging beyond the collars of the pipe ends. An annular profiled seal forms an approximately U-shaped hollow profile with the shanks which are formed as sealing lips and which abut against the peripheral surfaces of the collars. The assembly of the profiled seal is difficult. The sealing effect is often impaired by the peripheral surfaces of the collars being no longer sufficiently even and smooth. These drawbacks are removed by the invention such that the profiled seal has an inner profiled section extending between the faces of the collars and that the outer surfaces of the outer profiled section surrounding the peripheral surfaces of the collars are reinforced at a guide ring. Thus, the particular sealing region is disposed between the faces of the collars. The assembly is simplified by the reinforced outer profiled section of the profiled seal.
