Abstract
ABSTRACT
A fastener made out of a strip of metal is used to establish a temporary connection between adjacent gratings such as metal components used to surface roadways for instance. Each side of the fastener has flanking attachments that point downwards, that are separated and opposite each other, and that fit into recesses in the gratings. The flanking attach-ments are parallel to each other in such a way that the top of the fastener is shaped like a U. The distance between the two flanking attachments it slightly greater than twice the width of an edging strip on the gratings. The flanking attachments are slightly longer than the edging strip is deep.
The ends of the flanking attachments are continuously flanged on the inside, so that displacement of the adjacent gratings relative to each other is prevented, and the fastener remains tightly in place against motions of the gratings.

17 ha flanking attachment in a known fastener of this type 18 (German OX 2 737 179) point outward. This design has 19 disadvantages. Gaps that cannot be filled in can form between the edge and flanking Attachments when the grating 21 is vibrated into the ground, resulting in a weak point. The 22 flanking attachments can alto get Kent out 50 far that they 23 cannot be extracted from the ruses in the writing, which 24 can therefore be ~n~rchanged only with difficulty or not at Z5 all. Furthermore, since the flanking attachment which are I it the form ox pro~ectiny hooks, are alto conical, their 27 contact with the gratings is only lunar and the slightest 28 displacement of the fasteners in relation to the gratings 29 will result in unsatisfactory connection.
