Can't buckle up in your Mercedes E-Class? Seat Belt Extender Pros extensions are the highest quality extenders on the market designed to help you fasten your seat belt. Just pick your favorite color and style, and you are ready to drive safely and comfortably again.

No more tickets for not wearing a seat belt, and no fishing for seat belt receptacles between seats. With a quick click on each end, buckling up is easy again!

This extender is ideal for Mercedes E-Class drivers and passengers who can't otherwise buckle their seat belts, which may include some plus-sized people, police, fire fighters, sheriffs, and law enforcement officers with bulky utility belts, passengers in NEMT vehicles, people with mobility impairments and others.

When it comes to safety, quality matters more. Seat Belt Extender Pros offers the highest quality extenders on the market: the best value in the premium category of seat belt extensions. We don't just offer the safest affordable extenders to add extra car seat belt length. With the smooth finish metal surface, the sleek design and available color choices, your extender will also blend in elegantly with your vehicle's interior.

Your safety is our top priority with no compromise. Unlike most belt extensions on the market, Seat Belt Extender Pros extenders are:

  • E4 or E8 Certified
  • manufactured in a US DOT-registered factory that is
  • in compliance with ISO/TS 16949:2009 for Manufacturing of Seat Belt Assembly and Components
  • manufactured to exceed international break strength test requirements for three-point seat belts.

We offer the widest variety of safety tested car seat belt extensions for your Mercedes E-Class, but we won't let your options get confusing. With industry leading expertise, we can offer step-by-step support to help you find the optimal length and style for your needs. We suggest selecting an extender that adds only the minimum length needed to buckle up.

Extenders are diverse and never universal. Did you know that seat belts are different throughout most Mercedes models? Your belt's metal tongue and receptacle shape depend on the seat itself and the manufacturing year of your Mercedes. Seat Belt Extender Pros has the expertise to make your search easy.

Our regular extender style is made out of woven seat belt webbing material just like the seat belts in your car. Rigid extenders stand upright.

Seat Belt Extender Pros is known for industry-leading expertise, the widest selection of extenders available, an uncompromising focus on quality, and boundless devotion to customer happiness. With a decade of experience as the category pioneer, we're always on the cutting edge of new safety and convenience features. Recognized as the #1 seat belt extension brand worldwide with an extensive knowledge base, we are here to help you wear your seat belt comfortably again.

This product is for those who otherwise can’t buckle up. The seat belt extender’s metal tongue should click into the receptacle of the vehicle’s seat belt and the seat belt’s metal tongue should click into the receptacle of the seat belt extender. However, read and abide by your car manufacturer’s owner’s manual prior to installation or use of this product, which may not be compatible with your car. Failure to read and abide by manufacturer’s warning regarding purchase, use and installation could result in serious injury. Adults and children who can use the existing seat belt should not use an extender. Such unnecessary use, including with child restraints, could result in serious personal injury or death in the event of an accident.
