Abstract From the Canadian patent

Abstract, Disclosed is an optical connector for high density arrays. A rotating mechanism is employed around the fiber ferrule in combination with a spring so as to engage one or more tabs on the connector sleeve. The rotating mechanism includes a serpentine type groove configuration which captures the tabs when the ferrule is pushed into the sleeve and releases the tabs when a longitudinal force is again applied to the ferrule.
