Knot blocking and unblocking device for blocking shoelace in tight position, has pull tab maintained at side of stop during making of knot using strands, and sliding until knot to form another knot, where tab is inserted between knots
The device has a pull tab formed by a loop creating an orifice permitting the sliding of a strand (9), and by another loop. A knot (12) is made by using short strands (9, 13), while maintaining the tab at the side of a stop (7). The tab slides until the knot in order to form another knot (14). The tab is inserted between the knots. The tab is pulled opposed to the nodes until it stops against a section of the stop to unblock the knots.
