Abstract: A connector for fiber optical cable inluding a ductile metal sleeve, a portion of the fiber optical cable adjacent its end being positioned within the sleeve, with the end of the fiber optical cable projecting from a hole through the end of the sleeve. The portion of fiber optical cable adjacent its end is stripped of substantially all insulation and sheathing, while a resilient tubular insert surrounds such portion which is adjacent the cable end, the tubular insert in turn being positioned within the metal sleeve. The metal sleeve is crimped to hold the sleeve, tubular insert, and stripped adjacent end portion together in immovable relation. By means of this invention connectors may be placed on optical cable, capable of withstanding excessive cable retention, without the use of adhesives.
