The tape knot, as its name suggests, is used to tie the ends of tape (webbing) together, usually into a loop for an anchor.

It is actually just an overhand bend tied in tape, but rarely known as such.

Note that tape knots can fail under cyclic loading/unloading, so you should make sure that the knot has sufficient tails (20 cm/8 inches) if you have a number of people abseiling off the anchor. You should also check carefully if you are using an anchor set by another party, as the margin of safety may have diminished.
