A contact spring includes a base spring including a spring arm base having two ends, two parallel side walls with ends, a connection part extending integrally away from the side walls at one end of the spring arm base, and spring arms extending integrally away from the side walls at the other end of the spring arm base. An overspring is retained on the spring arm base and has a bottom wall spanning the side walls of the spring arm base, and side walls peripherally adjoining the bottom wall, being parallel to the side walls of the spring arm base and extending around the ends of the side walls of the spring arm base. The base spring, in the vicinity of the spring arm base, and the overspring each having a top with at least one shaped tab joined to one of the side walls. One of the shaped tabs is retained by snapping under or underlapping another of the shaped tabs, forming a clamping device for securing the overspring and the base spring against mutual slippage.
