TetherGuard Extension Lock

Protect Sensitive Cable Ends and Keep Cables Connected 

The 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 JerkStopper Extension Lock around each end of the cable or cord, and then twist to lock the cords securely and safely together. 

The patented JerkStopper 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.

Included Rubber Washers 

The JerkStopper Extension Lock comes with two included rubber washers that further protect your cable ends, removing the stress and strain when pulled, ensuring the cable stays connected.
