Abstract:
1. A nut for screw connections, the nut comprising: two substantially identically sized nut segments of a half-shell shape, wherein the nut segments each have an inner side provided with an inner thread segment defining together an inner thread; wherein the nut segments are connected to each other so as to be moveable toward each other until the nut segments reach a closed position; springs maintaining a closed position of the nut segments; an actuating device moveably arranged on at least one of the two nut segments for releasing the closed position, wherein the actuating device is adapted to be manually actuated; wherein the nut segments in the closed position are loaded by the springs and wherein the actuating device is a spreading device that works against the springs; wherein the first lever is connected by a first rotary bearing to a first one on the two nut segments and the second lever is connected by a second rotary bearing to a second one of the two nut segments, wherein the first and second rotary bearings are arranged on a symmetry center of the first and second nut segments, respectively.
