Within examples, a wire clamping device includes a base. The base includes an indentation, a first attachment component at a first end of the base, and a second attachment component at a second end of the base that is opposite the first end. The wire clamping device further includes an arm that includes a protrusion and a third attachment component that is attached to the first attachment component. The arm is configured to rotate with respect to the first attachment component to a position at which the arm is restrained by the second attachment component against the base and at least a portion of the protrusion is within the indentation or aligned with the indentation. Additional examples include a method for using the wire clamping device, a tool for opening the wire clamping device, and a method for using the tool to open the wire clamping device.
