Clamp for an optical fibre
A clamp for a plastic coated optical fibre comprises a tubular portion which is a fairly close sliding fit on the coated fibre and an axially split portion having at least one resilient axially deformable finger. The dimension across the split section is slightly larger than across the other portion. An axially split sleeve is axially slidable on the clamp, and is freely slidable along the tubular portion on to the slit portion. Sliding of the sleeve on to the slit section deforms the finger into gripping contact with the fibre coating and also expands the sleeve. This provides a "backing up" force and also accommodates variations in diameter of coated fibre. More than one finger can be provided, and serrations or other formations can be provided on the fingers.
