Abstract
A top hat rail is disclosed for fixing snap-fit apparatus, formed by shaping in the form of an omega a metal strip of predetermined thickness and having a web and two flanges. The flanges of said rail are deformed towards their free ends so that the edge of the flanges has, for the apparatus to be snap-fitted, a useful fictitious thickness, this thickness being determined between two support zones situated on each side of the flange. The fictitious thickness is equal to the thickness of a standardized rail and substantially greater than the real thickness.
