Abstract: An optical-fibre connector comprises a support piece 1, a first locking piece 2 and a second locking piece 3. Locking pieces 2 and 3 are respectively fixed to the support piece 1by screws 4 and 5 which are engaged in cylindrical bores containing sleeve of elastomer material. The locking piece 2 comprises at its base two bearings 8 and 9. To connect two series of optical fibres, two identical connectors are disposed end to end and connected by two spindles 10 comprising a threading 11 which engages in a metallic sleeve 12 containing a sleeve 13, made of an elastomer material. This assembly permits absorption of vibrations and limitation of the clamping in order to avoid breaking of the optical fibre during use or connection of the two series of optical fibres.
