You are looking for something like this (which at present doesn't do anything except exist 
)? By the way the coax screw adapter in your picture is available in the adafruit repository (which is separate from fritzing's). I can't immediately get Inkscape to only export the image (my png viewer was showing a large black background as well as the part)
well that turned out better here than in my preview anyway. I'll poke a bit at seeing if I can achieve making that "plug in" to a modified coax jack such that the wires on the end will connect to the leads on the jack (which is what the original person wanted, and what would be reasonable for Fritzing). Making the end of the tip transparent with connectors in it that mate to the jack may be possible to allow it to "plug in" in breadboard.
