Two pieces (1A,1B) form the connection between two end panels of two vertical partitions (2,3) formed by a central core (5) of insulating material between two facings (6,7). The pieces are connected by a zone of least resistance (10) defined on one of the facings. This zone corresponds to the top of an open triangular cavity in the opposite facing passing through the insulation to obtain a folding line (P) for one panel piece relative to the other. Longitudinal stiffeners (12,13) are located either side the zone of least resistance on the internal surface of the corresponding facing. This enables later manual folding to ensure a regularity of the fold along the panel length.
