Windscreen wiper device

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, which wiper blade includes at least one longitudinal groove, in which groove 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 can be pivotally connected to said connecting device about a pivot axis near one end with the interposition of a joint part, wherein said joint part comprises a pair of walls and a pair of tabs that extend from an end of the pair of walls and said joint part is adapted to be locked onto said oscillating arm, wherein at least one laterally inwardly extending protrusion provided on said oscillating arm is snapped behind at least one of the pair of walls of said joint part, wherein while said joint part is locked onto said oscillating arm, said joint part is pivotable relative to said connecting device between a wiping position and a service position, wherein:

• when in the wiping position, a part of said connecting device extends upwardly between the pair of tabs of said joint part, and said pair of tabs is blocked against bending laterally inwardly by the part of said connecting device extending upwardly;
• and
• when in the service position, said joint part pivots about the connecting device to position the pair of tabs away from said part of said connecting device that extends upwardly, and the pair of tabs is bendable inwardly to allow said pair of walls of said joint part to bend laterally inwardly to release said protrusion of said oscillating arm from said at least one of the pair of walls of said joint part.
