Flemish bend

The Flemish bend, also known as a figure eight bend, a double figure eight bend, and a rewoven figure eight is a knot for joining two ropes of roughly similar size.

A loose figure-eight knot is tied in the end of one rope. The second rope is now threaded backwards parallel to the first rope. When properly dressed, the two strands do not cross each other.

Although fairly secure, it is susceptible to jamming. If tied, dressed and stressed properly it does not need "stopper" or "safety" knots.
