Patent attributes
A flexible, integrally formed tie strip for forming a loop when passed through itself comprises a plurality of identical cells formed in a strip, the cells forming generally loop-shaped enclosed apertures (10) bounded by wall portions of the cells, each aperture allowing the passage of further cells through it. The cells are further provided with one or more latching members (11) allowing passage of one cell through another in one direction but preventing passage of the cell in the reverse direction. The walls (9) bounding the apertures can be folded to a saddle shape about radial 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 penetrating cell through the aperture of another cell. Moreover the penetrating cell is designed to fold so as to pass through still more easily. This three-dimensional deformation is promoted by a notch (15) in the rear of each aperture wall.
