Windscreen wiper device of the flat blade type

A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped,

• the wiper blade includes at least one longitudinal slit, in which slit at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for a rod-shaped extension of an oscillating arm, wherein said rod-shaped extension can be pivotally connected to said connecting device about a pivot axis near a free end thereof,
• wherein said connecting device comprises a first part and a second part, wherein said rod-shaped extension of said oscillating arm can be pivotally connected to said first part about said pivot axis, with the interposition of said second part, wherein said first part is connected to said wiper blade and said second part is pivotally connected onto said first part, wherein said second part comprises a channel arranged to receive said free end of said rod-shaped extension,
• said windscreen wiper device comprises a housing for said rod-shaped extension, wherein said housing is arranged to be connected to said second part, and wherein said housing comprises a channel to receive said rod-shaped extension, said channel of said housing in mounted position being co-axial with said channel of said second part, wherein said first part and said second part are provided with mutually cooperating pivot means for pivotally connecting said second part to said first part, and wherein said first part engages said second part laterally from the outside at the location of said pivot axis;
• said windscreen wiper device comprises a two-part retention mechanism for securing the rod-shaped extension to the connecting device, said two-part retention mechanism comprising a first retention means and a second retention means;
• said first retention means comprising a bayonet connection formed by connection of a resilient tongue arranged on the second part of said connecting device with a first hole arranged on said housing, wherein said resilient tongue is hingeable along a hinge axis between an inward position retaining said wiper blade onto said rod-shaped extension and an outward position releasing said wiper blade from said rod-shaped extension;
• and
• said second retention means comprises a second connection formed by at least one protrusion arranged on the first part of said connecting device and a second hole formed in the rod-shaped extension, wherein the at least one protrusion extends away from the first part of the connection device in a direction opposite from the wiper blade.
