Abstract
A fixing element has a shank having a rear end and a leading end, a holding element arranged on the rear end of clamping an article to a building component, at least one expansion region extending from the leading end in a longitudinal direction for part of a length of the shank. The expansion region is formed by a longitudinal slot with a base surface raising toward the leading end. A expansion member is inserted in the longitudinal slot. The base surface slopes upwardly and ends at an outer circumference of the shank at a distance from the leading end. The expansion member is formed as a wedge with a length substantially corresponding to a lenght of the longitudinal slot and lies on the base surface so as to be displaceable toward the leading end. The wedge has an outer surface provided with roof-shaped teeth which project beyond the shank at least by a part of a height of the teeth.
