Abstract

The invention relates to a connection device (10) for the articulated connection of a wiper blade (28, 30) to a wiper arm, wherein a connection element (12, 120, 126) is tightly connected to the free end of the wiper arm, and the connection element is connected in an articulated manner via mounting means (88, 122, 124) to an adapter (22, 24), and the adapter is tightly seated on a support element (28) of the wiper blade (28, 30). It is suggested that a base cover (18), which surrounds the adapter (22, 24) and which can be attached to the adapter or to the support element (28), has a guide rail (66) running in the longitudinal direction (136), and that a push-spring (16) is mounted thereon and is adjustable in the longitudinal direction (136), and that the push-spring can be attached to a guide block (112) of the base cover (18) in different positions with different offset distances (114, 116, 118) in the longitudinal direction (136) of the guide rail (66) by means of locking means (68, 70, 72), wherein the guide block is connected to the end of the guide rail (66) on the wiper arm side.
