Abstract
Two optical fibres are connected in end to end relationship by positioning the fibres in a tubular connecting member, the member having a preformed section which has a number of lobes formed in the tube, the radially inward extremities of the lobes defining an axial bore into which the uncoated ends of the fibres can slide. After positioning the fibre ends in the preformed section the plastic coating of each fibre is gripped by crimping the tubular member. For a splice both coated fibres are crimped into a single tubular member. For a releasable connector two tubular members are used, one incorporating the preformed section, and the two tubular members each crimped on to a fibre, the two members held together.
