Windscreen wiper device

1. A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove in which a longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis near one end thereof, with the interposition of a joint part, wherein said windscreen wiper device comprises a cover element mounted onto said connecting device and pivotable about a longitudinal axis which extends at approximately ninety degrees to said pivot axis between a closed position wherein an open end of the connecting device is covered and an open position wherein the oscillating arm can be mounted onto or removed from the connecting device through said open end, wherein the cover element is U-shaped in cross-section with spaced side walls joined by a base wall, and wherein a rib extends perpendicularly from said base wall spaced between said side walls such that an edge end of said rib is adapted to trap the oscillating arm between said edge end and said joint part, wherein the base wall of the cover includes a U-shaped opening facing towards the joint part.

2. The windscreen wiper device according to claim 1 , wherein the connecting device and the cover element have mutually cooperating protrusion and recess features for maintaining the cover element in closed position.

3. The windscreen wiper device according to claim 1 , wherein the joint part and the cover element have mutually cooperating protrusion and recess features for guiding during closing of the cover element on the joint part.

4. The windscreen wiper device according to claim 1 , wherein the cover element is a cap.

5. A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade, which can be placed in abutment with a windscreen to be wiped, a carrier element including at least one longitudinal strip, which windscreen wiper device comprises a connecting device and a joint part pivotally coupled to said connecting device for attachment with an oscillating arm, and including a cover element mounted movably by rotation about a longitudinal axis of the windscreen wiper device onto said connecting device between a closed position wherein an open end of said connecting device is covered and an open position wherein the oscillating arm can be mounted onto or removed from the connecting device through said open end, wherein the cover element is U-shaped in cross-section with spaced side walls joined by a base wall, and wherein a rib extends perpendicularly from said base wall and is spaced between said side walls such that an edge end of said rib is adapted to trap the oscillating arm between said edge end and said joint part, wherein the base wall of the cover includes a U-shaped opening facing towards the joint part.

6. The windscreen wiper device according to claim 5 , wherein the connecting device and the cover element comprise at least one mutually cooperating protrusion and recess for maintaining the cover element in closed position.

7. The windscreen wiper device according to claim 6 , wherein the joint part and the cover element comprise at least one mutually cooperating protrusion and recess for guiding during closing of the cover element on the joint part.

8. The windscreen wiper device according to claim 5 , wherein the cover element is a cap.
