Abstract

A nut for a screw connections has, in the circumferential direction, segments that are substantially of the same size, abut one another in separating planes, and are movably guided relative to one another between an open position and a closed position. Closing elements serve for movement of the segments toward one another into the closed position. In order to provide a segmented nut that is suitable for many applications in facility and apparatus engineering, the segments are pivotable relative to one another and connected for this purpose in a first end area in a pivotable way. The closing elements load the segments in the second end areas.
