The presence of the magnetic shield does not clutter the space left by the claw for the translational insertion of the permanent magnet.
- the invention also covers a wiper blade of a vehicle wiping system comprising at least one adapter as described above.
- the adapter is directly linked by a pivoting link to a connector which carries the wiper blade.
- a wiper blade provided with such an adapter can therefore be fitted on any type of vehicle equipped with the wiper arm complementary to the wiper blade and which allows a mechanical and magnetic connection.
- the invention also covers a vehicle wiper system comprising a wiper arm and a wiper blade as previously described.
