Claim:
A method for establishing an electrical connection using a detachable plug-in connection, the method comprising: providing a contact element having a sectionally lengthwise-slotted shaft part, the shaft part having ribs arranged around a circumference of the contact element; providing a sleeve part adapted to surround the shaft part and covering the ribs, the sleeve part having two ends; positioning the sleeve part essentially coaxially relative to the shaft part for covering the ribs by the sleeve part; connecting the sleeve part to the shaft part at one of the ends by plugging the sleeve part over the shaft part; twisting the shaft part around a central axis of the shaft part such that the ribs bend inwards towards the central axis, the bended ribs formed as arcs; and locking the sleeve part to the shaft part at the other end, wherein the shaft part is held twisted against an elastic reset force caused by the ribs.
