The bracket consists of an upper part and a lower part. The upper part has several forms provided for positioning and fixing in the step or the step support consisting of wood or metal. The positioning of the upper part of the bracket is embedded in a housing in the step or the walking support. The lower part has several shapes provided for positioning and fixing on the metal stringer vertically. The positioning of the lower part of the fixing lug is ensured by a screwing system in the silt in which a threaded orifice is made. The fixing lug, its positioning mode and its method of attachment are particularly intended to fix the steps or the walking supports on the metal stair slats.
