Abstract: A slidable planer window cover that secures an optical connector in a fiber optic module. The cover is notched to form a rectangular opening, the notch defining two adjoining sides of the rectangle, a base and a base cover forming the other two sides. The window cover is slotted to allow a screw to pass through from the outside—with respect to the module—and be secured to the base on the other side. When the screw is tightened against the window cover, sliding motion is restrained. Flexible clips on opposing sides of the connector retain the connector within the rectangular opening when the window cover is secured by the screw in a closed position. When the screw is loosened, a removal tab on the window cover facilitates sliding the cover to the extent allowed by the screw, to enlarge the opening thereby facilitating removal of the connector.
