Abstract
Inside a container tube (7) which is closed by two covers (8, 8') fixed to the cables to be connected, this connection box comprises a cylindrical tank (27, 17, 17') for storing optical fibers (3, 3') with the inside cylindrical volume of the tank being delimited at each of its ends by respective conical surfaces (24, 24') leading to narrow passages (40, 40') through which the optical fibers (3, 3') pass on their way from the covers (8, 8'), said tank having a large side opening (27) enabling the ends of the optical fibers (3, 3') to be taken out from the tank for the purpose of being connected and then enabling them to be reinserted together with their connectors (28). In the vicinity of each of its conical ends, the inside volume of the tank has respective annular recesses (29, 29') of greater diameter into which the spare lengths of the optical fibers (3, 3') have a natural tendency to coil.
