Abstract:
The present disclosure describes a spring connection element, by means of which at least two components can be connected to each other by means of a claw-fit in at least one component opening. The spring connection element is characterized by the following features: a spiral spring-like wire coil with a first and a second end, said coil comprising a plurality of axially spaced windings, a spiral collar which extends radially beyond a circumference of the wire coil and which is arranged at the first end of the wire coil, and a central traction element protruding radially into the wire coil, which is arranged at the second end of the wire coil, which does not extend axially beyond the wire coil, and by means of which the spring connection element can be pulled into a component opening substantially rotation-free.
