<p>Device has cover (2) designed to jut out from the opening (12) in the side with a plate-shaped section, in such a way that between side's inner surface and the cover section through-channels (11) form a flow-operated hair trapping device. It has a clamping cage (7) with hinged mechanism which is adjustable using a fixed nut/bolt combination (4,5) along its axial length in such a way as to transform from an average length at the outset into a shortened assembled length. As a result of radial extension, it can be secured in the assembly casing or on the sides of the outflow casing, or vice versa when it can be changed into a lengthened dismantled state in which the arresting arms of the clamping cage are free from the assembly or outflow casing.</p> |
