Device for adjusting the fit and appearance of an article of apparel or hair and method of assembly

The fastening device comprising:

• at least one flexibly deformable wire, said wire comprising a first end, a second end and a body having a length from said first end to said second end, the wire substantially encased in a flexible coating,
• an elastically deformable tube mounted on said wire and substantially surrounding the body of the wire, the tube comprising a substantially cylindrical body, a first end, a second end and a length from said first end to said second end, wherein the length of the tube is substantially equal to the length of the wire,
• a cover mounted on said tube, the cover comprising first and second ends, wherein said cover substantially encloses said wire and said tube, wherein the first end of the wire is coupled to the first end of the tube and the first end of the cover, collectively forming a first end of the fastening device, and a second end of the wire is coupled to the second end of the tube and the second end of the cover, collectively forming a second end of the fastening device,
• wherein the user applies pressure to substantially the first and second ends of the fastening device to manipulate said device by bending or looping the device or twisting the first and second ends of the device to releasably lock said ends of said fastening device to each other into a locked position whereby the body of the tube maintains a substantially cylindrical shape when in said locked position and substantially along the entire said length of the tube,
• whereby when a break occurs in the wire, the break comprising at least two sharp wire points, the at least two sharp wire points remain encased in the tube and cover so as to inhibit the sharp wire points from protruding through the tube and the cover.
