ABSTRACT:
A security modular connector constructed to fit into a conventional jack or receptacle for use in securing a connection in a telephone or computer system, such as for connecting a telephone base unit to a telephone line. The security modular connector differs from a conventional modular connector in that the spring-biased tab which bears on a stop when in electrically-engaged relation with the jack or receptacle is cut off so that it does not protrude through the opening of the latter, thereby denying manual access to the tab. Furthermore, a flange on the outer end of the security modular connector substantially closes the opening in the jack or receptacle when the connector is in engagement with the former. Thus, unauthorized persons are denyed access to the line. A special tool enables authorized persons to pry open the security modular connector from the face of the jack or receptacle, and depress the spring-biased tab, releasing the security connector from the jack or receptacle.
