Abstract

A nut for screw connections has 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. The nut segments are connected to each other so as to be moveable toward each other until the nut segments reach a closed position. The nut segments are maintained in the closed position by springs or a locking device. An actuating device is moveably arranged on at least one of the two nut segments for releasing the closed position, wherein the actuating device is adapted to manually actuated.
