Abstract
In order to provide a joint connection, comprising a first joining piece with a first contact surface and a passage opening onto the first contact surface, and a second joining piece with a second contact surface and a recess opening onto the second contact surface, said first joining piece and second joining piece standing in a joining position in relation to one another, in which the contact surfaces abut one another and the passage and the recess together form a cavity, for joining pieces made from brittle materials it is proposed that a positive-locking element is disposed in the cavity; that the positive-locking element comprises a plastically inserted molding, which is cured in the cavity and abuts the joining pieces over their surface; that together with the first joining piece and the second joining piece, the positive-locking element forms a positive locking which secures the first joining piece and the second joining piece relative to one another in at least one direction of stress along the contact surfaces; and that the positive-locking element has undercuts which together with the first joining piece and the second joining piece form a positive locking which secures the positive-locking element in the cavity.
