Abstract:
1. A nut for screw connections, the nut comprising: segments extending in a circumferential direction of the nut, wherein the segments are substantially of same size, abut one another in separating planes, and are movably guided relative to one another between an open position and a closed position; a lever mechanism that moves the segments toward one another into the closed position; wherein the segments each have a first end area and a second end area, wherein the first end areas of the segments are pivotably connected to one another by a pivot joint so that the segments are pivotable relative to one another; wherein the pivot joint is a double joint comprising an intermediate joint member extending transversely to the separating planes; wherein the lever mechanism comprises a closing lever directly supported on a first one of the segments on a pivot axis so as to be fixedly but pivotably connected to the first segment and a further lever fixedly but pivotably connected to a second one of the segments, wherein the closing lever is fixedly but pivotably connected to the further lever and acts on the further lever for actuating the segments between the open position and the closed position, wherein the closing lever projects outwardly past an outer surface of the nut; wherein, in the open position, the second end areas of the first and second segments remain connected to each other by the lever mechanism; a fastening element rigidly formed on at least one of the segments for connecting a safety belt.
