  • Patent number: 5058984
    Abstract: A tubular connector body (10) has one end (11) for receiving an optical fibre cable (1) having a plastics outer sleeve (3) protecting an optical fibre (2) and carries at the other end (12) connection means (20) for coupling to another similar connection body. A ferrule (30) is mounted within the other end (12) of the connector body (10) to support an exposed end portion (2a) of the optical fibre (2) within an irradiation settable adhesive material (40) injected into the ferrule (30). A deformable gripping member (50) is inserted into the one end (11) of the connector body (10) to grip an end portion (3a) of the plastics outer sleeve (3) of the cable upon deformation of the gripping member (50) by application of a force to the one end (11) of the tubular connector body (10).
