Abstract: Detent devices for optical fibre members have an outer casing member with a tapered aperture in which an inner engagement member is slidably fitted. A strength member of the optical fibre member received in the inner engagement member can be wrapped back around a boss of the inner engagement member and is clamped by the slidable engagement member when the optical fibre member is pulled. Thus axial strain relief is provided.

Abstract: Break-out devices are provided for longitudinally extending elements. The break-out devices include a base member and a pair of ribs extending from the base member that define a longitudinally extending channel configured to receive the longitudinally extending elements therebetween. The inner sides of each of the pair of the ribs may include one or more longitudinally extending slots defining pairs of slots. A removable partition is inserted into the channel to provide a through-hole dimensioned to receive one or more of the longitudinally extending elements. The removable partition may be inserted in one of the pairs of slots. The partition may include a locking mechanism that retains the partition in the channel. Methods for organizing optical fiber elements using such break-out devices are also provided.
