A cable duct coupler includes an inner wall shaped to define a cable-receiving channel therebetween, a support rib extending from the inner wall and including at least one mount clip, an axially extending outer wall outwardly spaced from the inner wall to define a duct section receiving space therebetween, and at least one removable retention clip. The retention clip has arms that extend into the duct section receiving space, such that upon insertion of cable duct sections, such as a cable trough or fitting, into the duct section receiving space, the retention clip biases the duct sections against the inner wall to retain the duct sections together. The removable retention clip is movable between an insert position in which the arms extend into the duct section receiving space to allow coupling and a detach position in which the arms no longer extend into the duct section receiving space to allow disassembly of the discrete duct sections. The retention clip is formed of a resilient material such as metal and may be bent to form arms that are angled towards the support rib of the duct coupler. The arms may be sharpened or serrated at an edge thereof to increase retention of the duct section with the coupler. With this invention, an attachment end of a duct element, such as a trough or fitting, is able to be relatively easily slid in one direction into the duct receiving space and constrained by the inner and outer walls. However, the retention clips provide a retention force acting on the attachment ends of the duct elements that resist undesired disassembly of the duct element from the coupler in an opposite direction. However, disassembly, when necessary, can be achieved easily by removal of the retention clip, such as by unscrewing.

1. A cable duct coupler for coupling discrete cable duct sections together without the need for tools, comprising:an inner wall shaped to define a cable-receiving channel therebetween, said inner wall having a predefined axial length between forward and rearward edges; a support rib outwardly extending from said inner wall, said support rib being substantially centrally disposed between the forward and rearward edges of said inner wall, said support rib including at least one clip mount; an axially extending outer wall formed on said support rib, said axially extending outer wall being outwardly spaced from said inner wall by a predefined distance to define a duct section receiving space therebetween; and at least one removable retention clip matable with said clip mount through an open space provided in said outer wall, said retention clip having arms that extend into the duct section receiving space, wherein upon insertion of duct sections into said duct section receiving space, said at least one retention clip biases the duct sections against said inner wall to retain the duct sections together.
