Abstract
Within a ferrule inserting hole 21 of a housing 2, a stop groove 23 is provided, while a taper portion 24 is formed as an insertion stopper. A ferrule 3 inserted and held in the housing 2 comprises a substantially cylindrical optical-fiber holding section 31, an optical-fiber crimping section 32 adapted to be crimped by means of a crimping tool for connecting electric wires or the like, and a latch 33 which expands within the stop groove 23 when positioned therein so as to prevent the ferrule 3 from dropping out. Accordingly, a crimping tool used for electric contacts in typical electric works can be used for crimping and attaching an optical fiber 4 to the ferrule 3. The ferrule 3 having the optical fiber 4 attached thereto can be firmly held by the housing 2 by simply inserting therein.
