Implement for cleaning or treating surfaces or for applying media to surfaces

An implement for cleaning or treating surfaces or for applying media to surfaces with a holder and a deformable disposable working part interchangeably gripped by said holder, the latter comprising a sleeve and a sliding part guided thereon, a handle on an end of said sliding part projecting over the sleeve, and grippers for gripping the working part arranged at the other end of the sliding part, said grippers being displaceable in a first direction from an unobstructed, open position projecting over the sleeve into a use position for fixing the working part and by means of said handle said grippers can be moved via said sliding part in a second, opposite direction for releasing the working part, wherein the grippers and sleeve are constructed in such a way that the grippers grip the working part solely by mounting thereon and by pressing by means of said sleeve and are displaceable into the use position by deformation thereof in the held area, wherein said sleeve is in the form of a tube which is widened at its upper end to form a gripping tube, said handle being formed as a cap engaging over the gripping tube and which on engaging on the gripping tube determines the spread open position of the grippers, and wherein means are provided for axially adjusting the position of the handle relative to the sliding part for setting the maximum opening width of the grippers in said unobstructed, open position.
