Abstract

A continuous coupling element consists of an elongated filament of a synthetic resin or the like which is wound substantially helically to provide a multiplicity of turns with a row of spaced apart coupling heads formed along one longitudinal side thereof. Each of the turns further includes first and second shanks which when seen in a plan view, are curved arcuately in opposite directions, in such a manner that the first shanks of the respective turns partly overlap the second shanks of the preceding (or succeeding) turns and are connected to the second shanks of the succeeding (or preceding) turns via arcuate bights remote from the coupling heads. The continuous coupling element is to be fastened to one surface of a stringer tape as by a row of stitches extending along the overlapping portions of the first and second shanks.
