A reclosable cover for converting a two-piece electrical wire and cable duct system into a one-piece reclosable duct. The cover comprised of a dual-durometer plastic co-extrusion having a flexible hinge portion extruded of a resilient lower durometer plastic material. A clip assembly formed along one edge of the cover includes a modified .OMEGA.-shaped channel to receive and clamp the top end of a duct channel sidewall. Flexible fins are provided within this channel to further locate and retain the duct cover. A generally V-shaped hinge support member and dual ridges provide enhanced hinge integrity and an interference engagement therebetween to provide a cover 'remain-open' function. The clip assembly and support member share common elements to thereby improve on the space and cost efficiency of the duct cover.

Couvercle refermable servant à transformer un conduit à câbles en deux éléments en un conduit refermable en un seul élément. Le couvercle est obtenu par coextrusion de deux plastiques de duretés différentes présentant une portion charnière flexible en matériau plastique de dureté inférieure. Un ensemble de fixation par pincement, formé le long d'un des bords du couvercle, présente un évidement en forme d'OMÉGA pour recevoir et saisir le bord supérieur de la paroi du conduit. Des ergots flexibles à l'intérieur de l'évidement contribuent à positionner et retenir le couvercle du conduit. Le support charnière en V présente deux saillies allongées qui contribuent à l'intégrité de la charnière et dont l'interaction mécanique assure le maintien du couvercle en position ouverte. L'ensemble de fixation par pincement et le support charnière ont des éléments communs qui contribuent à améliorer les caractéristiques d'encombrement et de coût du conduit.
