A device for splicing multiple optical fibers includes a generally rectangular body (12) which is essentially comprised of a jacket (14) and a cap (16). Splice (10) also includes a splice element (18) and longitudinal actuation means (20) far applying pressure to splice element (18). In the preferred embodiment; actuation means (20) comprises a wedge (22) having surfaces defining an acute angle, which is captured between jacket (14) and cap (16). A tongue (24), which is integrally molded with cap (16), is advantageously interposed between wedge (22) and splice element (18) as discussed further below. Jacket (14) has a longitudinal slot (26), rectangular in cross-section and extending through jacket (14), for receiving a splice element (18)slot (26) is slightly shorter than splice element (18), allowing both ends of element (18) to extend beyond the ends of slot (26). Jacket (14) also has an integrally molded male coupling element or projection (28) which fits within a cavity (30) formed in cap (16). Projection (28) has two transverse bumps (32) which snap into recesses (34) of cap (16), providing a snug fit between jacket (14) and cap (16). Jacket (14) and cap (16) each have extensions (36) and (38), respectively, which receive end covers (40) and (42), respectively. Extensions (36) and (38) have recessed surfaces which support the fibers at the entrance to slot (26). End covers (40) and (42) impart protection to the spliced fibers and splice element (l8) against Environmental influences. End covers (40) and (42) are attached to extensions (36) and (38) of the jacket and cap, respectively, by any convenient means, such as arcuate jaws (44) which snap onto and rotatably grip trunnions (46). The end covers may advantageously include collapsible compartments filled with a sealant material whereby, when the covers are moved to the closed positions, the sealant material is channeled towards the slot containing the splice element.
