A clasp (20) for a biomedical electrode (12) includes opposed cooperating jaw members (23, 24). The jaw members (23, 24) can be end portions of a U-shaped leaf spring (30). A lever (40) is pivotally mounted for engagement with the jaws (23, 24) for forcing the jaws together to grip an electrode (12) placed between them. An opening (26h) is provided within the clasp (20) for receiving the stud (17a) of a different style electrode and a retaining tab or finger (30t) is provided for engagement with the stud (17a) to shift the stud to a locked position in the opening (26h) when the lever (40) is pivoted toward its operative or closing position.
