Abstract
A glass sleeve has a bore that, at its ends, provides a clearance fit around optical fibres to be coupled with said bore tapering inwardly to a link piece of glass optical fibre having the same cross-section as that of the fibres to be coupled and unto which the wall of the glass sleeve has been collapsed over substantially the entire length of the link piece. The glass sleeve is retained within the central region of a tubular member by a pair of pierced watch jewels disposed at each end of the member and having apertures that provide a clearance fit around the fibres and are in axial alignment with the sleeve axis.
