Segmented nut for screw connections

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;
• means for maintaining a closed position of the nut segments comprising two bolts supported parallel to each other in the nut segments for guiding the nut segments in parallel alignment, wherein, relative to the inner thread, the two bolts are positioned opposite each other relative to the axial plane, and further comprising a common locking element acting on the two bolts to lock the two bolts in the nut segments in the closed position, wherein the locking element is positioned between the two bolts in one of the two nut segments so as to be movable;
• and
• 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.
