Abstract

A windscreen wiper has a rubber blade, an beam being mounted on the rubber blade, multiple clips being mounted respectively through the beam, multiple spoilers being mounted on the beam, two end caps being mounted respectively on the spoiler and around the ends of the beam and the rubber blade and a connector assembly being mounted securely on the beam and between two adjacent spoilers. The beam that is held firmly on the rubber blade, and the clips hold the beam stably on the rubber blade. Therefore, the rubber blade is connected firmly to other components of the windscreen wiper, will not deform or deteriorate easily and has improved life span.
