An electrical connector assembly as defined in claim 2 wherein said wall partition having opposing flat wall surfaces that are parallel to one another. 4. An electrical connector assembly as defined in claim 3 wherein said frustro-conical, retainer includes a leading end, a trailing end and an intermediate portion therebetween, and said leading end includes a face portion having a central opening disposed in alignment with said outlet opening whereby said bushing flange is sandwiched between said face portion and said outlet end portion. 5. A duplex electric connector assembly comprising: a connector body having an outlet end portion and an inlet end portion, said outlet end portion defining a single outlet opening, said inlet end portion having at least a pair of inlet passageways disposed in side by side relationship, a partition wall separating each of the inlet passageways, a transition section connecting said pair of passageways in communication with said outlet opening, said outlet end portion, inlet end portion, said partition wall and said transition sections being integrally formed as a metal casting, a radially outwardly extending stop flange circumscribing said connector body between said inlet end portion and said outlet end portion, an outer retaining ring circumscribing said outlet end portion, means on said outlet end portion for retaining said outer retainer ring onto said outlet end portion, said retaining ring including locking tangs circumferentially spaced about the outer surface of said retaining ring, said locking tangs being blanked and cantilverely bent out of the surface of said outer retaining ring whereby the free ends of said locking tangs are directed toward said stop flange, conductor retaining means secured in each of said passageways for effecting unidirectional insertion of an electrical conductor into each of said passageways so as to prohibit unintentional separation of an electrical conductor from said passageway, said conductor retaining means comprising a sleeve frictionally secured within its corresponding passageway, and each of said sleeves having opposed inwardly angularly bent tangs directed toward said outlet opening for permitting unidirectional insertion of an electrical conductor into each of said passageways. 6. A duplex connector as defined in claim 5 and including a non-conducting bushing extending into said outlet end opening and said bushing is sandwiched between said outlet end opening and said outer retaining ring, whereby said bushing is prevented from being separated from said outlet end opening by said outer retaining ring. 7. A duplex connector as defined in claim 5 further comprising: a linear wall surface formed on each of the sleeves comprising said conductor retainer means; and opposing vertical surfaces formed on said partition wall separating each of the inlet passageways, whereby said linear wall surfaces and said opposing vertical surfaces engage. 8. A duplex electrical connector assembly comprising: a unitary connector body integrally formed as a metal casting having an outlet end portion, an inlet end portion and an intermediate transition section connecting said inlet end portion in communication with said outlet end portion, said outlet end portion having an outlet opening, said inlet end portion having a pair of side by side inlet passageways, each of said passageways having an inlet opening, a partition wall disposed between said side by side passageways, said partition wall having opposed flat wall surfaces, a radially outwardly stop flange circumscribing said connector body between said outlet opening and said passageways inlet openings, said outlet end portion having an outer surface sloping inwardly toward said outlet opening, a frustro-conical shaped outer retainer circumscribing said outer sloping surface, said frustro-conical outer retainer having a face portion having a central opening disposed in alignment with said outlet end opening, means for securing said frustro-conical outer retainer on said outer sloping surface, said frustro-conical outer retainer having a plurality of locking tangs formed out of said surface of said frustro-conical shaped outer retainer, said locking tangs being outwardly bent relative to said surface of said frustro-conical retainer, and a cable retainer sleeve secured within each of said passageways, each of said cable retainer sleeve being generally cylindrical configuration with a flattened side portion, said flattened side portion being disposed to complement said flattened surface of said partition wall in the assembled position, said cable retainer sleeves each including opposed cable retaining tangs blanked out of the surface of its respective cable retainer sleeve, said cable retaining tangs being inwardly bent at an angle relative to the surface of said respective cable retainer sleeve in the direction of said outlet end opening whereby said cable retaining tangs permit insertion of a cable therethrough and prohibits unintentional separation of a cable therefrom, and a non-conducting bushing fitted into said outlet end opening whereby said bushing is sandwiched between said face portion of said frustro conical retainer and said outlet end opening. 9.
