ABSTRACT:
A windshield wiper comprises a housing in the form of a U, carrying a pivot pin which cooperates in a recess formed in a driving head, together with a spring carried by a support element, with the said spring acting between the driving head and the shroud.
The driving head has an inclined groove, within which one end of a support bar for the spring is displaceable in sliding movement between a position in which the shroud is locked on the driving head, and a position in which it is unlocked and removable from the latter.
