Abstract
A snap hook that includes gate that includes and aperture that accepts a male portion that protrudes from the nose portion of the hook is disclosed. The coupling of the nose portion and the gate prevents the unwanted opening of the gate while the hook is under extreme loads. Still further, the use of a slide bar that is moved through translation and rotation when opening the gate of the hook is also disclosed. The translation and rotation motion provides improved cooperation of the components and improves the resistance of undesired movement of the slide bar by forces against a protrusion on the slide bar, and thus provides greater resistance to unwanted opening of the gate.
