Abstract
In a laminated glass sheet with a fixing device introduced into a through-hole for objects, particularly for antennas, the through-hole is made up of holes of different sizes in two rigid sheets of the lamination, and the fixing device includes at least two parts introduced into the through-hole, pressing against surfaces around the edge of the through-hole, which surfaces are situated one facing the other. The two parts of the fixing device press from both sides against the surfaces around the edge surrounding the smaller hole made in the sheet, in that region of the walls of a smaller hole that exhibits an edge compression stress that is increased by heat treatment by comparison with the remainder of the surface of the sheet.
