<p>PROBE COVER A protective cover which may be used with a sensor probe component of an electronic thermometer is provided having an improved design for a structure comprising two components of dissimilar materials. An elongate shaft or sleeve member preferably of plastic material may have a metallic cap member forming a closural end thereof. The metal cap may have a flange extending outwardly therefrom. This flange extension may traverse backwardly away from the shaft. Plastic material from the shaft is formed about the backward traverse of the cap flange to form an interlocked encasement of the two dissimilar components.</p>
