Disclosed herein is a fastening structure which enables objects to be easily removeably coupled, and enables a smooth slideable coupling and decoupling. The fastening structure includes a male and female component. The male component is cross shaped with a wing member and cross bar member. The female component has a complementary structure with an elongate slot and cross groove, such that the male component is slideably received and mated.

A lace tensioning device includes a housing component having an interior region, a first aperture, and a second aperture, and a spool component that is rotatably positionable within the interior region of the housing component. The spool component has a central cylindrical member and a lumen that extends through the central cylindrical portion. The spool component is rotatable within the interior region of the housing component to align one end of the lumen with the first aperture and to align an opposite end of the lumen with the second aperture to enable a lace to be inserted through the first aperture, the lumen, and the second aperture so that opposing ends of the lace are positioned exterior to the housing component. A knot may then be tied in the lace and the lace retracted to couple the lace with the housing component and spool component.

An apparatus, system and method have a shoelace with a length defined between two ends. The shoelace is made from an elastic material that folds to join at a seam extending lengthwise along the shoelace. A hollow core is defined in the shoelace and extends along the length of the shoelace. An aglet is attached to an end of the shoelace to insert into an eyelet in a shoe. The shoelace stretches in response to tension applied to the aglet. The shoelace stretches to accommodate insertion of a foot of a wearer into the shoe. The shoelace contracts to retain a foot of a wearer in the shoe. The shoelace extends in a direction away from the shoe to loosen the shoe. The shoelace is made from a synthetic fiber material.

Elongated bodies made from high tenacity polyolefin fibers are provided that are useful as fishing lines, and processes for making the lines. Fibers having tenacities of at least 39 g/denier are braided and fused together to form braided bodies having very small diameters.

A loosening prevention lace which overcomes the problems where the lace is slackened or undone upon the lace being tied up through the eyelets for fastening the shoes, garment and as such and which brings unforeseen effect on design or appearance as well. The loosening prevention lace is provided by weaving one picot forming linear body or a plurality of picot forming linear bodies into a tubular woven fabric in a warp yarn direction thereof and protruding one picot forming linear body or a plurality of picot forming linear bodies from a surface of the tubular woven fabric with a certain interval over a longitudinal direction of the tubular fabric in a loop form.
