ABSTRACT:
A tie strip is formed of a flexible resilient material in strip form, with regularly longitudinally spaced openings formed in the strip and a pair of oppositely directed pawl acting tongues projecting from opposite end edges of each opening toward each other. The strip, in application, is folded at its end about its medial axis and inserted in a selected opening and it is movable through the opening in only one direction when inclined to the strip at the engaging opening in such direction and is movable in the opposite direction upon reversal of the inclination, the opposite tongues functioning as opposing pawls.
Another embodiment has a series of longitudinally spaced openings formed in the strip with a tongue projecting from one edge of each opening facing an enlarged one end of the strip. The one end of the strip has an opening therein with inwardly directed sides having a pair of tongues projecting from opposite end edges of the opening towards each other. An additional embodiment has the opening in the one end of the strip with one tongue only projecting inwardly from the end edge of the opening facing the edge of the one end of the tie strip.
