An improved ECG electrode connector adapted for attachment to a biomedical patient electrode by either pinch or snap connection is disclosed. A closed-end electrical connector includes pair of pivotally connected members including a main connector body having an electrically conductive plate defining an electrode stud receiving aperture and disposed in proximity to the bottom surface thereof, and a jaw pivotally connected thereto and resiliently biased to a closed position. The jaw is adapted with a beveled surface that functions to urge the jaw in open by engagement of the top surface of an ECG stud thereby allowing the connector to be attached by snap engagement. The electrically conductive plate defines an irregular, generally oval-shaped opening that allows the electrode stud to be inserted through a wide portion of the opening and retained by the narrow portion of the opening. Positioning an electrically conductive plate at the bottom of the connector allows the connector to maximize electrical contact with the electrode stud. An ECG electrode connector in accordance with the present invention may further be fabricated of radiolucent materials.
