The channel being for the arrangement of a compensating portion of a press-fit contact element. The press-fit contact element has a press-fit portion, a compensating portion and a foot portion, the compensating portion being elastic in a longitudinal direction of the press-fit contact element and having at least two O-shaped sub-portions arranged in succession in the longitudinal direction and having a constriction arranged between two sub-portions.
