Abstract

A pipe clamping unit has a central clamping part with a lateral clamping part on each side of it. At least one clamping part can co-operate with an operating element to bring about motion of the part. The lateral clamping parts are coupled to the central clamping part in such a way that, on movement of this part, the lateral clamping parts also move, until the central part in its extreme position forms, together with the lateral clamping parts, a closed clamping unit. The clamping unit is very stable, of compact design and is simple to use and maintain.
