Learn why a seat belt stop button is essential for both safety and convenience.
Learn where it is, how to replace it fast, and what to do if it breaks.
The little button on a car seat belt may not seem like much, but it is essential to both convenience and safety.
A stop button, also known as a retainer button, is the little plastic element of the seat belt strap that keeps the metal latch plate—the part you click into the buckle—from sliding too far down when not in use.
What if there was no such button? The latch plate would just slide all the way down to the base, making it challenging to hold when it came time to buckle your seat belt.
This simple button keeps the latch plate in a handy place, saving you time and aggravation.

Where Can I Find the Stop Button?
Actually, there are two of these buttons on the majority of seat belts.
To stop the metal piece from sliding too far up toward the shoulder strap, one is placed near the latch plate, while the other is nearer the top to stop it from sliding down toward the floor.
Together, they make sure the seat belt stays in the right place when you need it.
If Your Stop Button Breaks, What Will Happen?
These buttons are easy to repair, however they might ultimately break off or wear out.
It is easy to install replacement buttons using basic tools, and they may be purchased online or at auto dealerships.
You hardly realize it until it’s gone, but it’s one of those little things. But once you see how much effort it saves you and how it maintains the seat belt in place, you’ll appreciate that button’s small but effective function.
