The invention demonstrates that devices with a displaceable adjusting area, devices made of an elastic material or those with flexible properties are suited for use as adjusting devices, and that for building such devices, stiff designs are unnecessary. Flexible designs are much easier to use. Since the adjusting area is displaceable, their openings can be easily placed in a better position for adjusting, and then placed in a position again that is better for holding. Elastic and flexible adjusting means can be used such as conventional adjusting devices, e.g. for creating adjustable dog leashes. |
