The invention relates to a separator plate for an electrochemical system, comprising a first and a second plate, which are essentially congruently arranged on top of one another. The first and/or second plates furthermore include at least one elongated projection, which protrudes on opposite sides from a plate plane of the separator plate and extends along the plate plane from an outer edge to an interior of the separator plate so that the projection of the first plate and/or the projection of the second plate, if necessary together, form a receptacle for a connector pin. The projection of the first plate or the projection of the second plate includes an indentation directed toward the respective opposite plate for fixing the connector pin in the receptacle in a force-fit and/or form-locked manner.
