These rails are interconnected by a plurality of closely spaced curved or chevron rungs (3) which define between them similarly shaped apertures (4). The free end (51) of the strip can readily pass through an aperture in a forward direction and form a closed loop, but when pulled in the reverse direction, the rungs engage to form a co-operative latch and thereby prevent withdrawal. ## Claims ### Claim 1 A multiple-use tie strip, formed in a ladder-shaped construction comprising two substantially linear side rails of generally uniform cross-section, the rails being interconnected by a plurality of spaced curved or chevron rungs which define between them similarly shaped apertures, wherein the tie strip is constructed such that a front end of the tie strip can pass through one of said apertures in a first forward direction and form a closed loop, but when pulled in a second reverse direction, at least two of the plurality of rungs form a boundary around said one aperture and engage to form a co-operative latch and thereby prevent withdrawal, wherein each of the plurality of rungs has a central part with an apex and side arms defining a basal portion that forms a rotation joint where each rung meets the side rails, and wherein the side arms are inclined at least longitudinally towards a rear end of the tie strip and vertically to create a double rake angle of each rung that points both backwardly and upwardly. ### Claim 2 (depends on 1) The tie strip according to claim 1, wherein the tie strip is formed from a polymer material. ### Claim 3 (depends on 2) The tie strip according to claim 2, wherein the tie strip is formed from nylon. ### Claim 4 (depends on 1) A tie strip according to claim 1, wherein the side walls are formed with a rhomboidal cross section with side angles of approximately 5° to 10°. ### Claim 5 (depends on 1) The tie strip according to claim 1, wherein the longitudinal and vertical double rake angle is approximately 30°. ### Claim 6 (depends on 5) The tie strip according to claim 5, wherein an aspect ratio of the rungs is adjustable along their length. ### Claim 7 (depends on 6) The tie strip according to claim 6, wherein the vertical double rake angle of one of the plurality of rungs is approximately 15° and the vertical double rake angle of another of the plurality of rungs is approximately 25°. ### Claim 8 (depends on 1) The tie strip according to claim 1, wherein the apex of one of the plurality of rung is at least level or overlaps the basal portion of an adjacent rung of the plurality of rungs. ### Claim 9 (depends on 8) The tie strip according to claim 8, wherein a distance of said aperture between the apex of the one rung and the basal portion of the adjacent rung is not greater than half the thickness of the side rail. ### Claim 10 (depends on 1) A tie strip according to claim 1, wherein a cutaway notch is provided on an underside of a rear portion of each rung. ### Claim 11 (depends on 1) The tie strip according to claim 1, wherein the apex of each rung includes a flattened section which widens a centerline portion of the rung. ### Claim 12 (depends on 1) The tie strip according to claim 1, wherein the tie strip has a tapered front end having a pointed tip leading to a tapered feed portion. ### Claim 13 (depends on 12) The tie strip according to claim 12, wherein said tip is provided with raised grips or knurls. ### Claim 14 (depends on 1) The tie strip according to claim 1, wherein a distance between the at least two rungs is approximately twice a thickness of the tie strip. ### Claim 15 (depends on 1) The tie strip according to claim 1, wherein the linear side rails have a substantially square cross-section. ### Claim 16 (depends on 1) The tie strip according to claim 1, wherein the rungs have substantially the same dimensions to the side rails. ### Claim 17 (depends on 1) The tie strip according to claim 1, wherein the at least two rungs are configured to close together and reinforce each other when the tie strip is used for latching. ### Claim 18 (depends on 1) The tie strip according to claim 1, wherein an overall width of the tie strip is approximately 6 to 8 times greater than a width of the side rails.
