<p>The holder has longitudinal and laminar supports (10) for a mob cover, and forming wisp contact surfaces on opposite laminar sides of the supports. The supports comprise a magnetic fixing device i.e. magnet (17) for fixing the mob cover on the holder, and the magnet produces magnetic force on the wisp contact surfaces in a region of the holder. The magnet comprises a counter piece made of ferrite metal for the magnet in the mop cover, and is corrosion-resistant and provided with a plastic casing.</p> |
