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.

    If you have a E coup or converibile this doesn’t work

    Posted by Unknown on 24th Apr 2018

    Use this web site to buy this product as it was supposed to be customized for the specific car. My E Class is a convertible and as such has an arm that hands the seat belt from the back so you can reach it. Was hoping with this specific seat belt extension that are would still work as if not belt was connected BUT is doesn’t so have to reach behind my head to retrieve the belt and pull it forward

    Posted by Scotty on 5th Nov 2016

    Needed a little more room to get my fat fingers around stock seat belt connector. Ordered car seat belt extender based upon exact model of my Mercedes, Seat Belt Extender Pros asked for additional information and a photograph just to make sure metal end piece matched my car. A couple of clicks later my extender were installed, added 6 inches and cured my quick click problem, great product! Thanks.
