Each raceway stretch includes a base section, external walls; one or more compartment walls providing for the existence of sub-raceways, folds capping the walls and forming longitudinal slots and a cover section for each sub-raceway. The internal bottom surfaces of each base section are coplanar and have juxtaposable end cuts over the whole extension thereof. The elbow includes for each sub-raceway, an angled closing member having skirts engageable simultaneously in longitudinal slots of both raceway stretches, closing portions of a sub-raceway of each stretch; and a covering member which, in said active position, covers said angled closing members from above and is provided with means for engagement with said base sections.

[ What I claim is:] [1.] An elbow for the angular connection of two stretches of raceway for electrical cable systems, each of said raceway stretches comprising; a base section defining an internal bottom surface; external walls; at least one compartment wall providing for the existence of at least two sub-raceways, said external and compartment walls being provided at the top end thereof with folds forming longitudinal slots; and a cover section for each of said at least two sub-raceways, provided with lateral skirts adapted to be inserted in said longitudinal slots; said internal bottom surfaces of each of said base sections; being coplanar and having respective juxtaposable end cuts over the whole extension thereof; said elbow being suitable to occupy an active position in which it establishes a connection between said two raceway stretches, characterized in that it comprises for each sub-raceway, an angled closing member having skirts which, in said active position, engage simultaneously in longitudinal slots of said raceway stretches, closing portions of said sub-raceway of each stretch from above; and a covering member which, in said active position, covers said angled closing members from above and is provided with means for engagement with said base sections.
