<p>The holder has an upper second edge (14,20) from which a ledge (30) extends radially outwards. The ledge engages on a part section of the periphery of the second edge and the holder has an arc-shaped collar component (50) pivotably connected to the housing wall (12,18). The collar component is pivotable from a first position, in which it is turned away from the ledge, into a second position, in which it at least partly overlaps the ledge. The collar component and the ledge, provided the collar component is in its first position, enclose an opening between them, which is smaller than the open end of the recess (26) limited by the second edge.</p> |
