Locking device

A locking device for connector housings, comprising an actuating handle and two locking elements that are rotatable on two bearing pins arranged on a first connector housing half and lockable on two locking pins arranged on a second connector housing half, wherein the two locking elements respectively consist of a one-piece wire element, wherein each locking element is realized in the form of a C-shaped limb with two limb ends that are initially bent inward and can then be connected to the actuating handle in a parallel alignment such that they perpendicularly intersect the C-shaped limb, wherein the limb features on the first limb end a part that is realized in the form of an open eyelet and serves for encompassing one of the two bearing pins, and wherein the limb features on the second limb end a bend, the end region of which is provided as a slide-on curvature, as well as a part that is realized in the form of an indentation and serves for producing a snap connection with one of the two locking pins of the second connector housing half.
