A device () for securing a support structure such as solar module-carrier () to a flat roof () which is provided with a non-bearing insulation layer () covered by a sealing strip (). The device () has an upper connection element () for the support structure and a spacer member () which can be guided through an opening () in the insulation layer () in order to support the connection element () on a roof substructure (). The spacer member () is anchored by a plurality of anchoring parts () on the roof substructure (). The connection element () comprises an upper and a lower connection flange () between which the sealing strip () is clamped. The spacer member () is designed as a profile or hollow-profile part which can be cut to length as required and is produced as an extrusion part from a thermal insulation material.

A nail retaining strip for feeding nails into a fastening element driving tool where the nails are driven individually out of the tool by a drive piston includes guide bushings for the nails. Adjacent guide bushings are separably interconnected by connecting webs. The guide bushing extends in the axial direction of the nail shank and has axially and circumferentially extending circular guide surfaces for supporting the nails within the muzzle bore of the driving tool. The connecting webs extend radially outwardly from the guide surfaces so that the guide surfaces on adjacent guide bushings are in spaced relation. The connecting webs retain the nails in the axial direction of the muzzle bore by engagement in a receiving recess in the bore located opposite a passage through which the nails are inserted into the bore. Such axial retention permits complete utilization of the nail strip down to and including the last nail.
