A double-plate combiner for a head-up visor, including two substantially flat plates substantially parallel to each other, and held fixedly together by a holding structure that includes a central baseplate, two side flanks connected to the central baseplate, and two spacers respectively connected to the side flanks and tightly holding the two plates between them. An outer plate is tightly held between free ends of the spacers and an inner plate is tightly held between the free ends, connected to the side flanks, of the spacers. An assembly of the plates, the side flanks, and the spacers has a plane of symmetry substantially orthogonal to the mid-plane of the plates. A first dimension from one spacer to the other of the outer plate is greater than a second dimension from one spacer to the other of the inner plate. The mid-plane of each spacer is not orthogonal to the mid-plane of the plates. Such a double-plate combiner can especially be applied to a head-up visor mounted in the cockpit of an aircraft, preferably of the airplane type.
