<p>The broom, wiper or similar cleaning unit has a releasably attached handle (12) and a cleaning head (2) and an elastic coupling with three-point bracing. The bottom of the handle has a T-shaped attachment (7, 8) whose crosspiece (7) has downward projecting tips with inward-projecting claws which fit into suitably shaped cutouts in the rear of the cleaning head (2). The interlocking joint so formed is made tight by the end of the handle (15) bracing itself against the rear central section of the head. This may be achieved by screwing the handle end through the internally threaded portion (8) of the T-shaped attachment.</p> |
