ABSTRACT:
A screen wiper element of generally elongate form, which is typically a screen wiper arm, comprises a body defining a longitudinal housing or recess, which is open in the lower face of the wiper element facing towards the swept surface such as a windshield. The longitudinal housing receives a feed pipe for supplying washing liquid to at least one spray device for spraying washing liquid on to the swept surface. The housing defined by the elongate screen wiper element includes a profile in the form of a groove complementary to the profile of the feed pipe.
