ABSTRACT:
A wiper blade holder has a main yoke which is provided with a single through hole for selectively receiving either one of differently dimensioned pivot pins. In particular the pivot pins have latching means, e.g. in the form of annular recesses, with which first or second latches selectively interengage in dependence on which pivot pin is received in the through hole. To support a small diameter pivot pin within the through hole at least one bush is fitted within the hole to reduce the diameter of the latter.
