Abstract From the Canadian patent

Optical fibres to be spliced are aligned by being pushed into the ends of a tubular housing in which they are secured by being pushed by resilient elements into a V-guide. The resilient elements may be spring tongues pressed out of one wall of a housing faces of which also form the V-guide and a number of V-, guides may be assembled into a common housing where a multifibre cable is being spliced. The housing in each case allows lateral access to the point of abutment of the fibres so that a gluing or refractive index matching material may be applied.
