The splice closure includes a tubular protective case having front and back covers. The left and right ends of the back cover are configured to form integrally therewith left rear and right rear half end seals, which are adapted to mate with separately-formed, left front and right front half end seals. Left front and right front half end seals are formed to fit inside the left and right ends of the front cover. The separately-formed, left front half end seal is secured to the integrally-formed, left rear half end seal, with a first set of cables clamped between the mating surfaces thereof. Likewise, the separately-formed, right front half end seal is secured to the integrally-formed, right rear half end seal, with a second set of cables clamped between the mating surfaces thereof. The two cables are spliced together and the front cover is bolted in place over the back cover/spliced cables/end seal assembly to form the protective case. Before the two covers are bolted together, a sealant is disposed between the mating surfaces of the front and back covers and between the outer surfaces of the separately-formed, left front and right front half end seals and the interior surfaces of the front cover to prevent extraneous material, such as water, dust, debris, snow, etc. from entering the protective case.
