Abstract: A sleeve for protecting the splices between waveguide cores or optical fibers, which cores or fibers are received in groups or bundles which in turn are received in a light waveguide cable characterized by a housing having an entrance for each of the cables, said housing containing a plurality of removable plates with a single plate for each group of individual light waveguide cores or fibers, said plates being arranged in the housing in spaced relationship with each of the plates containing a plurality of holding elements for the splices between the light waveguide cores and guide pins for holding the excess lengths of the light waveguide cores in loose loops on the plate. Preferably, the sleeve includes a comb adjacent each of the entrances for spreading the individual bundles or groups of individual light waveguide cores to the spacing between the plates.
