Abstract
The sleeve for protecting the splice (4) in telephone cables (2) and (3) is made up of two half-shells (1a, 1b) joined together by their adjacent edges, around splice (4). These adjacent edges are provided with a groove which, in the position where the shells are joined together, defines a duct, devices being provided for injecting into this duct a pasty material creating watertightness between these adjacent edges. The opposite ends (9, 20) of the sleeve are provided with jaws (11, 12, 13) for securing axially the ends of the cables (2, 3) to the sleeve and with devices for creating watertightness between these cables and these ends (9,10) of the sleeve. Each of the ends (9,10) of the sleeve bears at least two detachable jaws (11, 12) defining between them a chamber (18) connected with the above-mentioned duct.
