ABSTRACT:
A first plastic component and a second plastic component are joined together by an expansive joint system on the first plastic component and a driving joint system on the second plastic component. The expansive joint system has two expansive units while the driving joint system has corresponding driving units. When the driving units simultaneously expand the respective expansive units to a predetermined point, the expansive units contract to their original position and securely lock onto portions of the second plastic component.
