1. A stator for an electric machine comprising:
a winding including a plurality of interconnected conductors which are assigned to one or more phases, wherein an end of at least one of the conductors projects axially or radially beyond the winding and wherein an interconnection ring having at least one support ring on which a plurality of bus bars are arranged is axially placed onto the winding, and the support ring is formed from a plastic and has a plurality of concentrically extending annular grooves in each of which one of the plurality of bus bars is arranged, wherein at least one end of each conductor is connected to a respective one of the plurality of bus bars, wherein at least one of the plurality of bus bars is captively held in a respective annular groove by a bus bar securing element which overlaps at least portions of the annular groove in the radial direction, wherein the bus bar securing element is a deformed staking element formed integrally with the support ring, and extends in the axial direction from the support ring between two adjacent annular grooves.
