The invention provides a locking wall hanger having a pointed end, which is designed to create a hole in the wall as the hanger is inserted therethrough. Whereas a self-boring tip penetrates the wall and embeds itself in the rear wall surface a mid-parabolic portion of the hanger is adjusted to provide a spring force for locking the hanger to the wall. In order to compensate for an undue tilt of the hanger in its final assembly position, the angle between a hook portion protruding from the wall's front side and shank portion penetrating the wall is smaller than 90.degree.. Further the invention provides an adapter piece being adapted to be supported by the hanger.
