ABSTRACT:
A method for sealing holes, involves fitting an essentially bushing- and/or tube-shaped plug into a hole and then the wall of the plug is expanded radially along at least one axial segment. In this method, the plug is positively anchored axially in the hole. By this method of producing an axially positive anchoring of the plug in the hole, not only is a tight fit of the plug in the hole achieved, but a mechanical movement of the plug relative to the hole is reliably prevented. A hole arrangement is tightly sealed with an essentially bushing- or tube-shaped plug in the hole having a radially spread axial part fitting tightly in the hole. Between the hole and the plug a locking arrangement with axially positive effect is provided. In a hole arrangement of this kind, not only is tightness ensured, but also piston-like displacement of the plug in the hole is prevented. The hole arrangement can preferably be so designed that the sealing and locking parts are provided axially at different points.
