A safety interlock for use in a medical device includes a central tubular portion defining a fluid passage for passing fluid through the safety interlock. An outer ring portion is adapted for mounting on the medical device. The outer ring portion is formed of a light transmitting material and includes at least one interposing surface. A connector portion connects the central tubular portion to the outer ring portion so that the outer ring portion is spaced radially outwardly from the central tubular portion in opposed relation with at least a portion of the central tubular portion. The safety interlock device is adapted for mounting in medical device in a path of electromagnetic radiation from a source of electromagnetic radiation for reflecting the electromagnetic radiation to a electromagnetic radiation detector when properly loaded on the medical device.
