Sleeve of plastics material for avoiding the splicing of electrical or communication cables, and process for ensuring the sealing capacity of such a sleeve

摘要

1. A sleeve of plastic material for protecting splices of electric cables or telephone cables, comprising two half-shells (1a, 1b) assembled together along their adjacent edges (2a, 2b), the edge (2a) of one half-shell (1a) being provided with a longitudinal rib (12) engaged within a groove (13) formed in the adjacent edge (2b) of the other half-shell (1b) and sealing means being provided between said edges, characterized in that the groove (13) has an inner side wall (14) of sufficiently small thickness to be flexible, in that the height (H) of the rib (12) which is engaged in said groove is slightly smaller than the depth (P) of the groove, in that the face (12a) of the rib (12) which is adjacent to the inner face (14a) of said flexible wall forms with said inner face an angle (a) of a few degrees having a vertex (15) located at the extremity of said wall, the space defined by said angle (a) being filled by a strip of putty (16) which is deformed and compressed between said faces of the rib and of the wall.
