Abstract
The windscreen wiper device includes a longitudinally extending wiper element that is made of an elastomeric material. A carrier element, which includes at least one pre-curved longitudinal strip, operably supports the wiper element. The wiper device also includes a connector device with a first piece and with a second piece. A joint part is also provided, and the joint part is connectable with the second piece of the connector device and is configured for attachment with an oscillating wiper arm. The second piece includes a pair of prongs which extend through aligned openings in the first piece and the at least one longitudinal strip. Ends of the prongs are plastically deformed to lock the first and second pieces of the connector device with the at least one pre-curved longitudinal strip.

A windscreen wiper device, comprising:
- a longitudinally extending wiper element made of an elastomeric material;
- a carrier element including at least one pre-curved longitudinal strip operably supporting said wiper element;
- a connector device with a first piece and a second piece;
- and
- a joint part which is connectable to said second piece of said connector device and is configured for attachment with an oscillating wiper arm;
- said second piece including a pair of prongs which extend through aligned openings in said first piece and said at least one pre-curved longitudinal strip, a first portion of said prongs extending at an angle relative to a second portion of said prongs, wherein said second piece of said connector device has a pair of co-axially aligned protrusions that are received in co-axially aligned openings in said joint part to allow said joint part to pivot relative to said connector device;
- said pair of prongs being plastically deformed to lock and fasten said first and second pieces of said connector device with said at least one pre-curved longitudinal strip.
