Abstract
A fastening arrangement and fastening element for fastening together two or more members, at least one of which is concave with respect to the others. Fastened within an aperture in at least one of the members is a channeled fastening element with a longitudinally extending anti-jacking member and one or more additional members are attached to the fastening element by an elongated retaining element extending into the fastening element channel and locking therewithin. The anti-jacking member is proportioned to substantially extend between the concave member and the surface of the adjacent member to prevent jacking of the fastening element from the aperture.
