No. No special attachment for the nose cone. Most of us just drill a few holes through the tube and into the nose cone and secure it that way with some metal screws, until we move up to dual deployed, then we replace the metal screws with Teflon shear pins or Teflon screws. The ejection gases will shear off those Teflon screws and deploy your main chute when used in conjunction with an altimeter or a timer. The holes you drill into the body tube at the nose cone will need to be strengthened and made pretty solid with medium CA glue so that the pins shear and the paper tube doesn't tear. If you don't want to drill holes yet, the you can secure the nose cone with tape around the outside of the rocket just before flight. Don't count on a friction fit to hold the nose cone in place.
