Two of these locking clips are included to provide a more secure connection between the HDMI cable and your component.
Each well-made cable features 100% shielding and gold-plated connectors. To ensure reliable connections, Planet Waves includes a pair of their ingenious HDMILok locking clips, which securely lock the Planet Waves cable to any component with an HDMI lock screw. (See photos here to see how they work.) "E" series cables are extremely flexible, and are rated for in-wall installation.
