The present invention relates to a corner protector, e.g. for a sheet of glass, having a pair of generally triangular side walls (23, 24) connected by a pair of substantially perpendicular bridging walls (25) and (26). The internal faces of the bridging walls are substantially flat and are separated by a recess (15, 35). Internal channels (16) are provided along the junction between the side walls and the bridging walls, which reduces stresses at the junction between the side and edge faces of a protected article during impacts with the corner protector. The margins (27) of the side walls which extend between the outer ends of the bridging walls are curved such that they are mutually offset from each other for most of their length.
