ABSTRACT:
A jointing box for optical fiber cables comprises two generally funnel-shaped flanges having an internal profile matching the external profile of the sheath jointing the ends of the cables and the cable ends themselves. At least one heat-shrink material tube is shrunk onto the flanges. The flanges have peripheral grooves on their larger diameter end part around the sheath and their smaller diameter end part around the parts of the cables adjacent the sheath. Each heat-shrink material tube is coated on its inside surface with a sealing material which fills the grooves on the flanges.
