| 1. A device for a releasable electrical connection of a contact pin with a sheet metal component, wherein the sheet metal
component (40) has at least one opening (41), the device comprising:
a contact element (1) including a sleeve (10) placed in an electrically conducting manner in the opening (41), the sleeve (10) including an interior detent (14);
a spring element (20) enveloped by the sleeve (10) and adjacent the interior detent (14), wherein, in a mounting position, the contact pin (50) is received by the spring element (20) in the sleeve (10), and the contact pin (50) is connected in an electrically conducting manner with the sheet metal component (40) via the spring element (20) and the sleeve (10);
a locking ring (30) disposed within the sleeve (10) and disposed on a side of the spring element (20) that is opposite the interior detent (14), the locking ring (30) formed as a longitudinally slit clamping sleeve, and
in an area of the locking ring (30) the sleeve (10) having an interior diameter which is widened in comparison with an area of the spring element (20).
