Abstract: A clamp for long-handle floor-washing wipers or scrub-brushes, which comprise an elongated head for a wiper blade or brush carried at the end of a broomstick, the clamp being adapted to releasably hold a rag and prevent its slipping-off the head during use. The clamp is comprised of two springy arms, spaced from each other and extending in alignment in a common plane, and a frame holding the arms by the respective extreme, outer ends thereof. The distance between the inner, free ends of the arms is slightly less than the diameter of the stick. When the clamp is mounted, with the stick squeezed between the free ends of the arms, the arms become flexed, thereby displacing the frame into either an engaging or a disengaging position with respect to the wiper head.
