TetherGuard Extension Lock

The TetherGuard Extension Lock is an effective locking device for cables and cords that keeps your cable ends protected from frustrating disconnects, damage, and electrical hazards. The simple clam-shell design enables you to simply close the TetherGuard Extension Lock around each end of the cable or cord, and then twist to lock the cords securely and safely together.

The patented TetherGuard Extension Lock protects the sensitive electronic cable ends and stops unwanted disconnects for USB extension cables, HDMI cables with couplers, and protects power cords for lighting and tools.
