Buckle Boss Heavy Seat Belt Lock & Guard — Universal Fit, Childproof Security Made in USA

The Buckle Boss Heavy Seat Belt Lock & Seat Belt Guard is a sturdy, childproof device that secures the seat belt release button to prevent accidental or intentional unbuckling while driving.

Designed by Buckle Boss and manufactured in the United States, this heavy-duty seat belt guard was created to give caregivers, parents, drivers, and professionals a reliable way to keep passengers safely restrained. With a category history stretching back to 2001 and more than two decades of use, the device is compact, easy to transfer between vehicles, and intended to block access to the buckle release without changing how the belt restrains a passenger.

How does the Buckle Boss stop passengers from unbuckling?

The guard clips over the seat belt mouth and covers the release button so fingers can’t press it while the vehicle is moving. It doesn’t interfere with the belt’s locking mechanism; it simply prevents the button from being pushed without first removing the guard.

• Durable molded housing resists tampering and handling.
• Childproof design deters curious hands and reduces accidental releases.
• Allows normal belt tension and movement while blocking the release tab.

Is it easy to install and remove in everyday use?

Yes — the Buckle Boss installs without tools and can be transferred quickly between seats. A small key (or any narrow, sturdy object) is provided to access the free slots and unlock the unit when a caregiver needs to release the belt.

• Snap-on installation fits common car, SUV, and van buckles.
• Quick-release with a key or slim object for authorized caregivers.
• Lightweight enough to carry and store when not in use.
