A windscreen wiper arm, particularly for automobiles, includes a mounting head mountable on a drive shaft and an arm member pivotally connected to the mounting head by means of a pivot pin. The arm member has a substantially U-shaped cross-section near the pivot pin comprising two side walls. A part of the mounting head extends between the side walls and beyond the pivot pin. Protrusion/groove features are provided on the part and the side walls for limiting a pivot angle of the arm member. The protrusion/groove means comprise at least one groove and at least one protrusion cooperating with the groove, the protrusion is movable in the groove between a first position corresponding with a wiping position of the arm member and a second position corresponding with a mounting position of the arm member. The part is provided with opposite abutting surfaces for abutting against the side walls. The protrusion extends laterally inwardly from one of the side walls into the groove being provided on one of the abutting surfaces abutting against that respective side wall. The groove has a width larger than a width of the protrusion.
