The fitting has a dowel and an expander (10) which is placed in an expanding or detaching position by turning or tilting the fitment (8). The dowel (6) has a plate (7) on which the fitment is mounted by an axle (11). At least one eccentrically shaped edge of the fitment rests against the plate. The fitment acts as holder for a drawer front panel or rail. It may have a covering plate with hooks at the ends gripping behind the plate's ends.
