On the inside it includes at least one central channel (C1, C2) closed at both ends and situated at some distance from the dorsal reinforcing member (D) towards its wiping edge or lip and fed with cleaning fluid by a pipe (C3) situated in its middle part, this blade further being provided on each of its two lateral sides with at least one longitudinal line of equidistant nicks (E) emerging in the central longitudinal channel, as well as with a longitudinal flap (V) situated and designed to direct the jets of fluid leaving the nicks substantially parallel to the corresponding side of the blade and in the direction of the glass to be cleaned. <IMAGE>
