The invention relates to a sleeve-shaped metal anchor (1) which can be expanded by introducing an expanding element (11). The invention also relates to a holding element (14) applied, for example, as an adhesive drop, which holds the anchor (1), during overhead assembly, in an upwardly directed borehole so that it does not fall out due to gravity as long as the anchor (1) is not yet expanded. |
