Abstract
A traction mechanism utilizing a tube of flexible material possessing an inner chamber which includes a dimension that is reducible in size upon the application of tension to the tube. Likewise, the tube chamber dimension is expandable in size upon the application of compression on the tube. The first end portion of the tube extends from a closure and terminates in a second open end portion. A tube may be formed of flexible material and possess a dual wall construction. A line extends from the first end portion of the tube to the second end portion thereof for attachment at that point. Pulling the line compresses the tube and thus increases the dimension of the same, releasing items held thereby in traction.
