Abstract
A connecting element for producing a structural connection between a first structural part and a second structural part by a foamable material, the connecting element includes a plug-in part and at least two chambers separated from one another in a fluid-tight manner by a partition, the at least two chambers each accommodating a reactant; a plug-in delimiting part mechanically connected to the plug-in part and configured to delimit displacement of the plug-in part in the plug-in direction; and a break-open mechanism configured to damage the partition, as a result of a break-open force supplied to the break-open mechanism, such that the fluid-tight manner between the at least two chambers is canceled, wherein reactants are selected such that mixing thereof causes a foaming reaction, which extends radially outward beyond the circumferential surface of the plug-in part.
