A reusable cable tie comprises an elongated strap, made of semi-rigid plastic material, and a buckle, made of rigid plastic material, for interlocking with the elongated strap. The elongated strap includes a first end a second end, an inner side and an outer side. The inner side incorporates a rack with a multiplicity of teeth, alternating with a multiplicity of grooves. The multiplicity of teeth extends from the first end up to a flat indented zone adjoining the second end that is provided with several teeth and grooves, the several teeth projecting from the outer side in an external zone corresponding to a beginning of the flat indented zone. The buckle incorporates a cavity so shaped and sized as to allow a passage through of the first and the second end of the elongated strap. |

1. A reusable cable tie comprising
an elongated strap, made of semi-rigid plastic aterial, and a buckle, made of rigid plastic material and intended for interlocking with said elongated strap, the latter comprising:
a first end a second end;an inner side and an outer side;
said inner side comprising a rack with a multiplicity of teeth, equally spaced and transversely located with respect to the direction of said elongated strap, each of said multiplicity of teeth having in cross-section a triangular shape, said multiplicity of teeth alternating with a multiplicity of grooves, equally spaced, each of said multiplicity of grooves having a shape and a size corresponding to each of said multiplicity of teeth;said multiplicity of teeth extending from said first end up to a flat indented zone, incorporating into said second end;said second end having several teeth, alternating with several grooves, the former and the latter being compatible to intermesh with a corresponding number of teeth and grooves of said multiplicity of teeth and said multiplicity of grooves, said several teeth projecting from said outer side in an external zone corresponding to a beginning of said flat indented zone;said buckle having a shape of a rectangular parallelepiped incorporating a cavity delimited by top, bottom and lateral sides, an entrance and an exit;
said cavity being so shaped and sized as to allow a passage through of said first or said second end of said elongated strap, or both when superposed; and, in order first to wrap and then to tighten said elongated strap around an object, said buckle is retained in said flat indented zone, at a lower part of said cavity, with its several teeth projecting upwardly; and after the tightening is completed, said first end of said elongated strap is inserted through said cavity, above said second end and, finally, said buckle is so displaced that said several teeth penetrate corresponding grooves of said multiplicity of grooves. |
