<p>A cover part (10) of a hand-held telephone or other corresponding device often carried in the pocket, whereby at least a part of the smooth outer surface parts of the cover part are provided with a friction surface (18, 20, 36, 38, 40, 44, 46, 54, 58). The friction surface is formed by a sticker or other corresponding thin plate-like material which can be fastened to the cover part. The sticker comprises a base material (26), on whose outer surface there are fastened with the aid of a binding agent (28) particles (30) with sharp edges, such as aluminium oxide, quartz sand, glass sand, metal oxide, or a corresponding material. Advantageously the sticker (24), intended to be fastened on the outer surface of the cover part, has a release film (32) on its adhesive side.</p> |
