US Patent 7153033 Coupling device for glass fiber connectors

A coupling device for glass fiber connectors has a front panel (2,4) and at least on coupling (1,1′,1″,201,207), which can be inserted into the front panel from the front face (20,40,202) and can be locked by means of latching springs (14,14′,14″,214). The latching springs engage behind the front panel (2,4). The coupling (1,1′,1″,201,207) can be released from the front face and, in addition to plug openings (21,41) for the couplings, the front panel (2,4) for this purpose also has openings (22,23,23′,42,47,45,46) for releasing the couplings from the front face.
