Abstract: The present invention describes a connection system for prefabricated panels of the type comprising at least two outer concrete layers (12, 14), provided with metallic reinforcement (18), and an intermediate layer (16) made of heat-insulating material, arranged between the two outer concrete layers (12, 14). The system comprises a plurality of plate-like connection elements (10) having such a length (L) as to allow them to extend, in an orthogonal direction with respect to the panel's development plan, through the heat-insulating layer (16) and to partially penetrate inside the outer concrete layers (12, 14). Each connection element (10) is provided, at two opposed terminal ends, with respective hooking means (22, 24) to the outer concrete layers (12, 14). At least one (24) of the hooking means provided at the opposed terminal ends of each connection element (10) is made up of two distinct C-shaped edges (24A, 24B), side by side and parallel to each other.
