Abstract: An electrode clamp (10; 100) for making contact with a film electrode and a snap electrode has a first part (12; 112), a second part (14; 114), and a contact element (60; 160). For clamping a film electrode, the two parts (12, 14; 112, 114) can be pivoted toward one another. In an initial state of the electrode clamp (10; 100), the first part (12; 112) and the second part (14; 114) have an offset (36; 136) relative to one another. The offset can be reduced by movement of the second part (14; 114) relative to the first part (12; 112) to such an extent that the snap electrode can be inserted into the electrode clamp. By a reset motion of the second part (14; 114) relative to the first part (12; 112) in the direction of the initial state, the snap electrode can be clamped against the contact element (60; 160) and contact can be made with the snap electrode. The electrode clamp (10; 100) can be connected in a mechanically detachable manner to the snap electrode.
