The invention relates to a connecting device (10) for connecting a joining element (46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66) of a wiper arm to a wiper blade (12) in an articulated manner, the supporting element (16) of said wiper blade being rigidly connected to a connecting element (20) of the connecting device (10). The connecting element (20) has at least one mounting web (26) which runs in the longitudinal direction, protrudes into the interior of an adapter (36, 38, 40, 42, 44), and supports a mounting pin (28) that runs transversely to the longitudinal direction. The adapter (36, 38, 40, 42, 44) is pivotably mounted on said mounting pin by mounting means (88), and the adapter (36, 38, 40, 42, 44) is detachably connected to the joining element (46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66). According to the invention, the mounting web (26) is formed on one longitudinal edge of a base (22) of the connecting element (20) only in a short region on the outer end of the connecting element (20), and the mounting pin (28) is secured on the mounting web (26) in cantilevered manner towards the other longitudinal edge of the base (22), while a lateral web (30) is formed on the other longitudinal edge of the base (22) in an offset manner with respect to the inner end of the connecting element (20).
