A device for connecting at least two lengths of trunking includes a plate for joining backs of base sections of the trunking. The plate has on each of its edges adjacent cut edges of the trunking base sections longitudinal tongues which bear on two opposite faces of each back. The tongues are substantially plane, have a thickness from about 0.2 mm to about 1 mm, and bear elastically against the opposite faces of the back.
