BOWLINE

n. loop that does not slip

The bowline is a simple knot used to form a fixed loop at the end of a rope. The structure of the bowline is identical to that of the sheet bend, except in the bowline the end and the standing part are used to form the knot rather than two ends, as in the sheet bend.
