The fluidic coupling member is movable in the bearing plane perpendicular to the longitudinal axis of the cowl, including the cowl member, by a maximum of 1 cm, preferably a maximum of 0.5 cm. Preferably, the fluidic coupling element is movable in the bearing plane perpendicular to the longitudinal axis of the cover, in particular of the cover element over at least 0.1 cm, preferably over at least 0.2 cm . This makes it possible to have particularly limited mobility of the fluidic coupling element relative to the cover, in particular, to the cover element. In particular, this will have the advantage of limited mobility in a plane of the fluidic coupling element relative to the cover, in particular to the cover element.

According to another feature, the wiping device comprises a bearing unit for movably receiving the fluid coupling element at least on the cover and which has at least one bearing recess and at least one bearing extension in it. a bearing recess. Preferably, the bearing unit comprises at least two bearing recesses, in particular, identical. Preferably, the bearing unit has at least two bearing extensions, in particular identical.

The orienting rib is preferably on the side not facing towards the wiper blade adapter. Preferably, the orientation rib is provided to orient at least one fluidic coupling element when this fluidic coupling element abuts against the cover element, in particular by the pivoting due to an adjusted connection of the element. fluid coupling with the fluidic connection element. As the hood is rotated, the fluid coupling member may abut the wiper blade adapter and thereby abut the cowl member to be reoriented and connected to the link member. The mobility of the fluidic coupling element is advantageously combined with simple assembly / disassembly.

According to another feature, the bearing extension is made in one piece with the fluidic coupling element. The fluidic coupling element preferably has one and in particular two bearing extensions, in particular for hooking into a bearing recess or two such recesses.

In particular, the bearing extensions 50c, 50c "and the bearing recesses 48c, 48c" viewed along the pivot axis 32c have a concave 56c arc shape.

The bearing extensions 50c, 50c "are in particular rounded, notably circular in shape for the middle part 58c and 58c" if one considers along the pivot axis 32c. The rounded middle portions 58c, 58c "are provided in the bearing recesses 48c and 48c" to make the rotation of the bearing extension 50c and 50c "easy to turn. The side segments 78c, 78c ’, 80c, 80c’ starting from the middle part 58c and 58c ’viewed along the pivot axis 32c. The side sections 78c, 78c ", 80c, 80c" are intended to limit freedom of movement, including the ability to turn and / or slide the bearing extensions 50c, 50c "into the bearing recesses 48c and 48c". The side parts 78c, 78c ’, 80c, 80c’ form in particular in the plane of the bearing, bearing extensions 50c, 50c ’in the form of a rib.
