ABSTRACT:
An anchor nut-cage fixing system is provided for positioning on a metal sheet from one of the faces of this metal sheet with a view to receiving bolts presented from this same face and comprising: a nut (1) with wings adapted for cooperating with an elongate hole (3) formed in the metal sheet (4); a plastic material cage (5) split by windows (6) and connected to an external collar (7). This collar is covered by a flat metal cap (9) perforated so as to let the bolts pass therethrough and having axially bent flanges (12) whose axial height is equal to or slightly less than the thickness of the collar, one at least of these flanges being bent to a little more than 90.degree. so as to imprison the collar.
