Patent ID: 7704587

Claim:
A flexible, integrally formed tie strip for forming a loop when passed through itself, comprising: a plurality of identical cells formed in a strip, the cells forming generally loop-shaped enclosed apertures ( 10 , 14 ) bounded by wall portions of the cells, each aperture allowing the passage of further cells through it, the cells being further provided with one or more latching members ( 11 , 13 , 26 , 27 , 31 , 33 ) allowing passage of one cell through another in one direction but preventing passage of the cell in the reverse direction, wherein the walls bounding the apertures can be folded to a saddle shape about transverse and longitudinal axes, so as to increase the width of the aperture without stretching the material of the walls, thereby facilitating the passage of a penetrant cell through the aperture of a further cell in use, and wherein the aperture is extended rearwardly by a notch in the rear wall portion bounding the aperture, the notch promoting the saddle shape fold of the walls of the aperture, and wherein a thickness of the rear wall of the aperture is substantially less at the notch than along the remainder of the aperture.
