Wiper blade

A wiper blade for cleaning motor vehicle windows has a wiper strip (12) which is surrounded by a guard profile (14) that with extensions (26, 28) formed onto its side cheeks (22, 24) engages longitudinal grooves (50, 52) of the wiper strip (12) and is fixed axially on the wiper strip (12) by inward-protruding protrusions (30, 32) in the region of its face ends (18, 20). The protrusions (30, 32) originate at one side cheek (22, 24) of the guard profile (14), and a first protrusion (30) extends on the outer face end (18) of the guard profile (14) to touch the opposite side cheek (22, 24) of the guard profile (14), while a second protrusion (32) on the inner face end (20) forms a gap (38) from the opposed side cheek (22, 24), which the gap allows mounting or unmounting of the guard profile (14) in the longitudinal direction (40, 42).
