ABSTRACT:
A device for establishing a flange connection, having a bearing which can act on a first flange, a counter-bearing which can act on a second flange, and a connecting lever between the two bearings is described. The invention is distinguished by the fact that the connecting lever is a lever with a drawing element. The drawing element and the lever each have a first and second end. The drawing element's first end engages the bearing and its second end jointedly mounts in between the first and second ends of the lever. The counter-bearing has at least one contact location for the first end of the lever and a recess for the drawing element.
