strip 18 is clamped between the wall of the bore 30 and the rivet 48 transmission of tensile forces no longer acts on the contact strip 18 the contact strip 18 is directly contacted with the electric connection 42 and as clearly shown in fig3 c the bore is closed the electric conductivity of the bolt or blind rivet is thereby not important in contrast to the alternative shown in fig2 this solution has the advantage that mounting of the rivet 48 is possible after assembly of the insulating glazing the bores 30 may at the same time serve as gas filling opening of the insulating glazing alternatively two bores may be provided in the structure of fig1 wherein the contact strip 18 is led out of the space 20 between the panes via a first bore 30 wherein the bore 30 completely penetrates through the spacer 22 and is closed by a stopper when the contact strip 18 has been guided through and a second bore is provided next to it which is formed in particular as a blind hole from the outer side of the spacer the strip 18 can be fixed in this second bore see fig4 to facilitate contact.
