The device includes an internal cover plate for the joint between the conduits. The fitting for linking together conduits or channels is intended to be used where two or three channels are joined together in mutually perpendicular positions in a corner. The channels may include two perpendicular horizontal sections (12B, 12B') and one vertical section (12A). A cover (19) is provided to fit over this corner, with a wider section (19A) fitting across the lower end of the vertical section (12A), and a narrow section (19B) fitting between the two horizontal channel sections. A base plate (20) fits beneath the joint, with pegs (21) for attachment to the internal surface of the cover plate (19).
