Until the Cable Guy comes, you can usually just push the connector back on. There will be enough friction to hold it without crimping it. There is some shielding which is braided steel on a good cable like TW usually installs. Just sort of fold that back towards the cable on the outside. When the connector gets pushed back on, the steel braid should contact only the metal of the connector. The heavy copper wire in the center of the cable should have a short length of its plastic insulation protruding a little farther out of the cable than where the outer insulation ends. That center wire and its insulation will go through a hole in the center of the connector. Get all of that ready and push it back on. Call TW if it's their cable. If it's your cable, buy a new one.
