The invention relates to a device (10) for the jointed connection of a wiper blade (12), having a wiper arm (18), wherein a connector (20) intended to be connected to the wiper blade (12) has a joint part (32) which forms a joint with a joint part (40) on a connector (38) intended to be connected to the wiper arm, and one of the joint parts (40) is a hub (40) open in the longitudinal direction of the associated component (20 or 28), the hub being supported with respect to the other component (38) in the direction opposite (42) the hub opening (42) when in the installed state, wherein the side walls (30, 56) of the connector (20) and of the connector (38) overlap. It is suggested that the side walls (56) of one component (38) has recesses (44) which are open to the wiper strip (14), and plunge into the projections (34) in the wiper blade (12) operating position, such that both components (20, 38) are locked against each other in the longitudinal direction.
