A member (1) secured in place by a fastening element (5) attaches insulation panels (2) to a structural component (A). The fastening element (5) is driven into the structural component (A) by a setting tool (8). To prevent damage to sector-shaped parts (6) extending radially inwardly in the entrance to a passageway (4b) through the attachment member (1), a diametrically increased section (4d) of the passageway extends axially inwardly from the entrance. The diametrically increased section (4d) has a diameter increased by twice the thickness of the sector-shaped parts (6) compared to the adjacent inward diameter of the passageway, and an axial length at least equal to the free length of one of the sector-shaped parts (6). When the muzzle end (8a) of the setting tool (8) is inserted into the passageway (4b), the sector-shaped parts (6) are bent inwardly within the diametrically increased section (6d) of the passage- way (4b) and, in combination with the passageway serve as a guide surface for the setting tool. The sector-shaped parts (6) rebound when the setting tool (8) is removed from the passage- way. When a coat of plaster (9) is applied over the insulation panels and the attachment members, the plaster penetrates behind the sector-shaped parts (6) and effects a back-gripping action.
