One or more optical fibers, forming part of a cable for the transmission of luminous signals, are divided into sheathed sections spliced together inside a junction box having opposite walls provided with a pair of nipples in which the incoming and outgoing cable portions are resiliently clamped. Between these nipples the two sections of each fiber, partly stripped of their sheaths, are bent into a loop along which they are joined together by a sleeve. Adjacent fiber loops of the same cable can be separated within the box by interposed sheets. The loops not only relieve stresses on the bared fiber ends but also facilitate the equalization of ray paths in a multifiber optical cable.

A device for splicing together sections of at least one light-conducting fiber forming part of respective portions of an optical cable, each of said sections being provided with a surrounding sheath, comprising: relatively fixed supporting means engaging said portions at points spaced from the ends of their respective fiber sections; and junction means engaging said sections at their free ends for establishing a continuous light path therebetween, said sections being bent into a closed loop with said sheaths stripped away in the vicinity of said junction means, the latter being positioned substantially midway of the loop.
