The invention relates to a coupling accessory for trays carrying electrical conductors, comprising a base part (2) and a cover part (3) which can be coupled to one another to form a coupling opening (4) for the end of a tray. A recessed overlap zone (6) is formed in the coupling opening (4) in order to cover the end of the inserted tray and said zone, together with the rest of the base part (2) and/or the cover part (3), forms a transverse step (7) serving as an insertion end-stop for the tray (5). The base part (3) is provided with: a securing through-slot (8) on each side of the central portion (6A) of the recessed overlap zone (6); and an insertion recess (9) at points along the upper edge of the sides (1B), for a press-fit tooth (9) provided on the cover part (3). |
