The invention relates to a connecting device (10) for a wiper arm (14) and a wiper blade (12). Said wiper blade comprises a first connecting part (16) on the wiper blade end and a second connecting part (18) on the wiper arm end, both parts being juxtaposed in the operational position and being connected to each other via a hinge element (44) so that they can be swiveled about a hinge axis. Securing means (32) are provided so that the first and second connecting part (16, 18) engage with each other. The invention is characterized in that the first connecting part (16) has a recess (38) for accommodating the securing means (32) in which a longitudinal, shaped portion (66) is provided which is parallel to the hinge axis. The invention also relates to a flat bar wiper blade (12) which comprises a first connecting part (16) for fastening the flat bar wiper blade (12) to a wiper arm (14). The connecting part (16) comprises a counter-hinge element (42) so that the flat bar wiper blade (12) can be connected to the wiper arm (14) so that it can be swiveled about a hinge axis. Said flat bar wiper blade is characterized in that a recess (38) for accommodating a securing means (32) is provided in which a longitudinal, shaped portion (66) is provided which is parallel to the hinge axis.
