A device for splicing multiple optical fibers includes a novel splice element (18) having two plates (74, 76) formed from a sheet of ductile material, there being a fold line in the sheet forming a hinge, the two plates being folded toward one another to define opposing surfaces. One of the opposing surfaces (76) has several fiber receiving grooves (82) therein, parallel with the fold line, and the other surface has ramps (88) at each end to support the fibers proximate the transition from their buffered portions to their stripped portions. The ramps are adjacent porches (84) which are integrally formed with one of the plates, the porches having additional grooves (86) for aligning the fibers with the fiber receiving grooves. Stop pads (90) are provided on both opposing surfaces, at the corners of the plates, to insure a clearance space at the ends of the plates which provides for more gradual clamping of the fibers, reducing insertion loss. Splice element (18) may be formed from a sheet of deformable material, preferably a ductile metal such as aluminum, although polymeric materials may also be used. Material selection is described further below. Certain features are embossed, coined, stamped, molded or milled into element (18).
