Adjustable-length tie-wrap
View Patent ↗Tie-wraps of practically infinite length are disclosed that can be cut to any desirable size at the time of use. These tie-wraps allow wrapping of any size object and comprise a flexible strap part and a locking part, both of which can be reused numerous times. To use the tie-wrap, the user cuts a piece from the flexible strap bundle and inserts its ends into a locking part and pulls one or both ends of the strap until it is tightly wrapped around the object. In other embodiments the ends of the strap may enter the locking part from one side or from multiple sides. In alternative embodiments the locking part or the strap may have a single pawl or multiple pawls which are made of plastic, metal, or other materials. Disclosed tie-wraps may be used, in addition to wrapping, to form handles or tag holders for the wrapped object.
