A wiping device includes an elongated wiping blade of elastically yieldable material, a handle, and an arrangement for replaceably mounting the blade on the handle, including an elongated mounting member of U-shaped cross-section which is supported on the handle and which bounds an elongated cavity and an elongated slot communicating the cavity with the exterior of the mounting member. The wiping blade has two marginal portions extending longitudinally of the wiping blade and each having a pair of wiping edges. The thickness of each of the marginal portions exceeds that of a central portion, and the width of the cavity exceeds that of the slot so that, when one of the marginal portions is received in the cavity and the other marginal portion can be located exteriorly of the mounting member, the latter is used for wiping and the former prevents extraction of the wiping blade through the slot. The mounting member may have arms which extend to different distances from the bight interconnecting such arms so that each of the arms reinforces the wiping blade against the bending to a different extent. The marginal faces of the wiping blade which face away from one another may be concave to improve the wiping action of the wiping edges.
