There wouldn't be any need to tap a hole for screws. If you do want to go that route, just drill a small hole (about 1/2 the diameter of the screw). PVC is a soft material and the hole will tap itself when you screw the screws in. If you want a less permanent option, you could just use zip ties. You'll probably need to attach 2 or 3 together to make it long enough to go around the tube, but their cheep. You can probably find a pack of a hundred for a buck or two at most hardware or automotive stores.
