Abstract: A retaining clip is used in combination with a wiper comprising a flexible wiper blade having a longitudinally extending headed rib and a resilient backing rail formed with a longitudinally extending and forwardly open narrow-neck slot in which the rib is received and captured, with an aperture opening at a back face of the rail spaced longitudinally from an end of the rail, and with a pair of laterally oppositely open grooves and having a back face directed away from the blade. A yoke assembly has a plurality of longitudinally spaced claws engaging over the rail and into the grooves thereof. The clip is unitarily formed with an end wall normally lying against the end of the rail blocking the slot thereof, a pair of parallel sides extending longitudinally from the end wall and normally lying over the grooves adjacent the end of the rail, and a pair of parallel arms extending from the sides and normally lying flat on the back face of the rail. These arms normally lie under a respective claw.
