A low-cost molded sleeve for a fiber optic cable connector receptacle is disclosed. The inner surface of the sleeve, into which a fiber optic connector can be inserted, is defined by three surfaces. A first planar surface and a second planar surface at right angles to each other form a V-shaped groove for holding the a fiber optic connector. Clamping action is applied to a third surface to hold the a fiber optic connector in place in the V-shaped groove such that optical coupling is achieved.
