flemish bend

More secure knots for this purpose are the Flemish bend, offset overhand knot, or double fisherman's knot.

I memorized filthy-sounding sailor terms like Flemish Bend, Double French Shroud, Chest Becket, Frapping Turns and Bag Lanyard.

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.
