Windscreen wiper blade stem in motor vehicles with lateral, intermediary and central levers connected by articulated joints and holders for mounting rubber element, characterised in that the lateral lever (2) has a transverse rectangular opening (4) in the middle part of its top and two profiled cut-outs in lateral walls; the central lever (1) has two longitudinal catches (11) and two opposite tongues (12); and the intermediary lever has in its upper part a rectangular opening (4) and two profiled cut-outs (5) in lateral walls, and its shorter external tip has a longitudinal catch (11) and two opposite tongues (12), whereas the connection of the central lever (1) with lateral levers (2) and/or intermediary levers (3) consists in placing the longitudinal catches (11) of the central lever (1) in transverse openings (4) of lateral levers (2) or lateral lever (2) and central lever (3) and bending the tips (14) of the tongues (12) in such a way as to insert them into profiled cut-outs (5) of the lateral lever (2) or intermediary lever (3).<IMAGE>
