Abstract: The invention relates to a semi-finished product for producing a three-dimensional component having a metallic base plate which has at least one predefined bending line, characterized in that functional elements are provided on the base plate in the region of a bending line, on both sides of the bending line, said functional elements making contact with one another when the base plate is reshaped along the bending line and permitting a connection.

Abstract: A connector is disclosed for providing a positive and/or a non-positive connection between at least two connecting partners. The connector or connecting means has at least one first region which engages with the first connecting partner by way of a positive and/or a non-positive connection, and at least one second region is provided which engages with the at least second connecting partner by way of a positive and/or a non-positive connection. The connecting means provides a positive and/or non-positive connection between at least two connecting partners in a simple and inexpensive manner and which meets high safety requirements. The second region of the connecting means has a region which is formed from an at least partially flat material made of an Fe alloy with shape memory characteristics and which, when activated, ensures the positive and/or non-positive connection with the second connecting partner by way of a change in shape.
