Abstract

A fastening spring that includes a tolerance zone and a restraint zone. The tolerance zone has a steep incline and the adjoining restraint zone has a flat incline. This allows for tolerance compensation that is increased by the disassembly strength. Furthermore, the fastening spring can be easily manufactured and allows for a damage-free disassembly and assembly of a first component into a second component.
