    Abstract: The invention is based on a link element (10) for windshield wipers, which is adjoined by a wiper rod (28) and is manufactured out of a metal sheet (16) by means of stamping and bending, in which, starting from a longitudinally aligned covering wall (40), at least one wall part of a side wall (38, 42) is comprised of a number of sheet metal layers produced by being bent inward by 180°, and a hanging device (32, 52, 54; 60; 58, 64) for a tension spring is fastened to the innermost sheet metal layer and protrudes into a free space (30) between the side walls (38, 40). The invention proposes that a slot (52) lateral to the longitudinal direction (56) of the link element (10) be let into the innermost sheet metal layer from the bottom edge (50) and that a pin (54) be inserted into this slot.
