Abstract
The present invention is a slip-knot grip device which attaches to a rope. The invention consists of a male end cap into which an insert is placed and a female end cap into which an insert is placed with the two end caps being connected by a retaining collar. The inserts have a semi-circle channel on their interior side placed so when the left and right inserts are connected together they form a circle opening through which a rope is placed. The female end cap and the male end cap are turned in opposite directions. This makes the end edges of the combined inserts clasp the rope holding the device in place.
