Wiping device and method of assembling a wiping device

The device has an adapter (10) i.e. wiper arm adapter, forming an articulation part (28) at a wiper arm or a wiping leaf (12). A set of form-closure elements (14, 16) of the adapter is connected with a form-closure element (18) of another adapter (20) i.e. wiper leaf adapter. A locking element (22) i.e. separate component, provides positive-connection between the closure elements of the former adapter and the form closure element of the latter adapter to deflect one of the elements of the former adapter. Another set of form-closure elements (24) of the former adapter is formed as a pin. An independent claim is also included for a method for mounting a wiping device.
