An adapter for connecting two wiring ducts on respective opposite sides of a suspended ceiling includes a back portion which has an opening at one end and upstream of the reference plane for inserting a first wiring duct. The other wiring duct can be butt-jointed to its other end. A cover portion at least partly covers the back portion, which has a reference plane which in use is level with the lower face of the suspended ceiling. Applications include conveying electrical cables or conductors through a suspended ceiling.
