Patent ID: 7470068

Claim:
A coupling for accommodating at least two plug-in connectors which are connected to fiber-optic cables, comprising: a coupling housing including a sleeve having a sleeve opening; a connection piece configured to couple to the coupling housing, the connection piece having an inner surface; and at least one moveable covering, which is assigned to the sleeve opening, wherein the covering, in a first position, covers the sleeve opening and, by the introduction of a plug-in connector, can be moved into a second position, in which the covering releases the sleeve opening, the covering comprising a bent metallic leaf spring, the leaf spring biased into the first position until subjected to loading, wherein a ferrule of the plug-in connector does not come into contact with the leaf spring at any point in time as the covering is moved to the second position, and wherein the covering includes wings that extend from the covering over an inner surface of the connection piece to secure the covering to the connection piece, the covering being planar when the covering is moved into the second position, and wherein the wings include tabs that are coplanar therewith and that extend toward the coupling housing, and wherein the wings define cutouts between the covering and the tabs such that the tabs are coupled to the covering by reduced width planar extensions.
