A clamp-type electrode contact for physiological use on animals including a first clamping member, a second clamping member, a connecting lead member, and a spring means. A spring engaging member disposed between first and second clamping members and connecting lead member may be included. Spring means is adapted for being placed in a first position when clamping members are in a closed position, and being placed in a second position when clamping members are in an open position. At least one inner side of clamping members includes engagement grooves formed along the inner side. Engagement grooves preferably form a crosshatch pattern, and each groove preferably has a rounded radius and is sufficiently shallow as not to introduce any epidermal or vascular trauma. First and second clamping members are generally aligned with one another whereby inner side of first clamping member and inner side of second clamping member face one another.
