Abstract
The invention relates to a tightening strap device for a heat-weldable plastic strip that is used to strap a packaged item and that is joined at a welding point to form a loop. Whereas in prior art the plastic strip is held during welding by several clamping elements, in the present invention the welding plate functions simultaneously as a clamping element.
