2115156 9305420 PCTABS00020 An optical fiber splice comprising a hinged splice element having two legs, at least one of the legs having a groove therein for holding the fibers to be spliced, a base for receiving the splice element, and a cap fitting over the base which has camming bars extending into the base and around the splice element, the caming bars urging the legs into a closed, clamping state. The camming bars are shorter than the splice element, applying the clamping force only to the center thereof, which allows the legs to flex open at their ends and apply a gradual clamping to the fibers. Alternatively, the camming bars may be thicker at their center and have inwardly facing surfaces which are convex, providing gradual clamping of the fibers which minimizes insertion losses due to microbending. The cap is provided with tabs which hold the cap in open and closed positions, the open position allowing insertion of the fibers into the splice elment, and the closed position causing the convex surfaces of the camming bars to forcibly contact the legs of the element and thereby clamp the fibers.
