A DEVICE FOR SNAP FITTING AN ELECTRIC APPARATUS ONTO A SUPPORT BAR

摘要

A device is provided for snap fitting an electric apparatus on a support bar comprising, in a case, a housing containing a blade spring and opening into a groove in which one of the edges of the support bar may be engaged against the action of the blade spring. This latter is disposed inside the housing so as to exert a transverse force on said edge and has, at its end situated towards the edge, at least one fastening step of a hardness greater than that of the bar.
