Abstract: A housing for a fiber optic splice, in particular, for a splice of the glass tubular type, includes mating top and bottom sections. The bottom section is characterized by two sets of four chamfered teeth positioned at either end and along the sides of a primary portion. A trough is formed in the primary portion so as to accommodate the contours of the particular splice to be encountered. The top section includes a center portion with walls extending upwards from both sides. Elevated members extend upward from the surface at each end of the center portion so as to provide, in concert with the chamfered teeth of the bottom section, an aperture through which a glass fiber may be inserted. Tapered tabs in the walls of the top section lock into longitudinal cavities cut out of the bottom section so as to maintain a relatively fixed relationship between the two sections.
