Abstract
A fastening device for attaching a structural member to a support member includes a lower portion having a shank portion attachable to the support member, and an upper portion having a radial flange at the outer side and an axial passage. The shank portion is insertable into the axial passage of the upper portion from one end thereof. At least one outer side of the shank portion has an axially parallel extending row of saw-tooth-shaped teeth, and a resilient pawl being formed at the axial passage for cooperating with the row of teeth in a ratchet manner, when the upper portion is pushed onto the shank portion in a first direction, to block a displacement of the upper and lower portions in a second, opposite direction.
