A connecting device for a pair of light waveguide cables with each cable having an optical fiber which is loosely enclosed in a tubular sheath characterized by a joint between the ends of the pair of sheaths of the two cables being bridged by an appropriate tube which is fixed to the ends of the two sheaths and does not require any special housing such as bushing and the like. The tube may be an inner tube, which is inserted into the interiors of the pair of tubular sheaths being connected together or an outer tube which is fixed onto the tubular sheaths. In another embodiment, both an inner and outer tube are utilized. A length adjustment of the optical fiber within the pair of tubular sheaths can be carried out by virtue of a helical arrangement of the optical fiber and the bridging which is provided by the one or more tubes.
A connecting device for a pair of light waveguide cables each having an optical fiber being loosely enclosed and arranged in a helical formation in a tubular sheath with an end of the fiber extending out of the end of the sheath, the device comprising the ends of the two optical fibers being butt-spliced together, an inner tube surrounding the butt-splice of the two fibers and having its ends being telescopically inserted into the ends of the sheaths to bridge the interval therebetween, and an outer tube having a longitudinally extending slot and being telescopically received on the ends of the sheaths, said outer tube being reduced in diameter to grip the ends of the sheaths so that the ends of the sheaths are supported by the inner tube as they are gripped by the outer tube.
