ABSTRACT:
Attachment elements to be fixed to panel-shaped structural components by a hardenable material include an axially elongated dowel sleeve (1) forming a passageway extending from a second end toward a first end. An axially extending annular part (2) encircles the dowel sleeve. A bag-like member (3) is secured to the annular part and to the dowel sleeve adjacent the first ends thereof. The bag-like member is inserted through a borehole in the structural component from an outer side thereof. The bag-like member can be filled with a hardenable material providing a gripping action with an inner side of the structural component. The bag-like member, when filled with the hardenable material, has a first side facing the inner side of the structural component and an oppositely facing second side with openings in the first side being larger than the openings in the second side. As a result, when hardenable material is injected into the bag-like member, it flows out through the openings in the first side and supports the bag-like member with large area contact with the inner side of the structural component.
