A continuous coupling element consists of an elongated filament of a synthetic resin or the like which is formed into a multiplicity of undulations including rows of first and second loops. A series of coupling heads are formed along one longitudinal side of the first loops, and the second loops are arranged along the other longitudinal side of the first loops. Each first loop further includes a pair of shanks which are arranged in substantially parallel spaced relationship in a plane perpendicular to the plane of the stringer tape. The general configuration of the first and second loops is such that they are held in contacting relationship at three dissimilar points for increased positional stability. The continuous coupling element can be fastened to the stringer tape by two rows of stitching, one passing over the shanks of the first loops and the other over the overlapping portions of the second loops. |
