A duplex electrical connector providing two inbound end apertures to
conduct two helically wound armored or metal clad electrical cables
through a single hole in an electrical junction box and secure it thereto.
The duplex connector includes a housing with spring steel cable retainers
at its inbound end to secure the cables and prevent their forceful
withdrawal from the box. A spring steel adapter is included at the
outbound end of the housing to provide easy snap-in attachment to the box.
Two embodiments include an insert for attaching the cable retainers to the
housing and a third embodiment includes a housing that accepts the cable
retainers without the need for a separate insert.
