Abstract
Abstract A fitting to be detachably fastened to a furniture part includes a fitting body to abut the furniture part, at least one dowel-like expansion sleeve which is anchored to the fitting body and which can be inserted into a drilled hole of the furniture part, and a pin shaped expansion member for expanding the expansion sleeve. The expansion sleeve projects through an opening in the fitting body, and the expansion sleeve also projects through the opening in the fitting body. The expansion sleeve is provided with at least one flap that projects in a radial direction from the expansion sleeve. The expansion member is provided with a head, which, when the fitting is mounted, presses the flap onto the side of the fitting body which faces away from the furniture part.
