Abstract
A plastic sleeve for protecting splices of telephone cables and electric cables against moisture comprises two half-shells (1a, 1b) assembled together. The edge (2a) of one half-shell (1a) comprises a rib (12) engaged in a groove (13) formed in the edge (2b) of the other half-shell (1b). One side of the groove (13) is formed by a flexible wall (14). The rib (12) which is engaged in the groove has an inclined face (12a) which forms an angle (a) of a few degrees with the inclined inner face (14a) of the flexible wall (14). The space formed by this angle is filled with a strip of putty (16) which is deformed and compressed between the inclined faces (12a and 14a).
