The invention relates to an apparatus for the detachable fastening of cleaning implements, e.g. brooms, scrubbing brushes or the like to a stick or handle. The stick is provided at its end with two fork-shaped, resilient arms, which can be fined in bores of the cleaning implement with the aid of a fining device. The fining device comprises a handle and an operating element located between the arms and which is in engagement with the latter by means of contact faces and spreads the latter outwards or draw them inwards by rotation or displacement. So that even after prolonged use a simple and easy adjustability is ensured, the contact faces of the operating element are constructed on rotary bearing parts, preferably bearing rollers or rolls, which roll on the arms during the adjusting movement of the operating element.</SD OAB> |
