- a wiper rod having a first end rigidly connected to and extending inside said wiper arm member and a second end arranged to be connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped;
- a nozzle for spraying a washing liquid onto the windscreen to be wiped, wherein said nozzle is detachably connected to said wiper rod inside said U-shaped cross-section of said wiper arm member, wherein a portion of said wiper rod near said first end comprises a hole;
- and
- a spring inside said U-shaped cross-section of said wiper arm member, wherein one end of said spring is arranged to be connected to the mounting head and another end of said spring extends through said hole in said wiper arm member, and said spring biases said nozzle towards the mounting head to mitigate longitudinal movement of the nozzle, tapering sidewalls of said U-shaped cross-section of said wiper arm member mitigate longitudinal movement of the nozzle in a direction away from the mounting head.
