Abstract
Abstract A fiber optic connector member having a removable front plate for protecting the faces of optical fibers mounted within the connector. The plate is retained within the connector shell by a resilient retention finger. The finger extends into a T-shaped slot formed on the outer surface of the plate. The slot opens at the front face of the plate. An extraction tool is disclosed which may be inserted into the slot to release the retention finger and grip shoulders formed on the sides of the slot allowing the plate to be withdrawn from the connector shell by pulling the tool forwardly of the connector.

Claim 1
Independent Claim
120 words
A tool for releasing and removing a support member from the front end of a connector shell containing a resilient support member retention finger extending inwardly and rearwardly from the wall of said shell into a slot between said support member and said shell comprising: a relatively rigid, flat retention finger releasing plate having a forward end and a rear end; a relatively resilient, flat arm extending along one edge of said plate in spaced relationship therewith, said arm being coplanar with said plate and resiliently laterally movable toward said plate, said arm having an inner edge adjacent to said plate and an opposite outer edge; and a hook on the outer edge of said arm coplanar with said plate.
Claim 2
Dependent Claim
