ABSTRACT:
Device for attaching two metal sheets or blanks together for absorbing the forces occurring particularly in ventilating systems to prevent loosening without requiring supplemental sealing means. The sheets or blanks to be fastened to one another are specially shaped and configured and are formed from blanks configured appropriately for the desired purpose. The clamped sheets are deformable in a corrugated-like manner in the region of clamping and within described parameters make it possible to secure previously unobtained extraction forces. The degree of bend and the angle and spacing between the legs determine the transmission of force.
