If your child restraint’s top tether or anchor strap is too short for your vehicle, the Maxi‑Cosi Child Restraint Extension Strap gives you the extra length you need. It solves installation issues without needing a new seat, and works across a wide range of cars — from compact hatchbacks to large wagons or SUVs. Available in two lengths (300 mm and 600 mm) to suit different vehicle configurations and anchor-point locations.
Two length options — 300 mm and 600 mm: choose the extension that fits your car’s anchor geometry.
Makes installation possible where tether reach is short — perfect for wagons, SUVs, or vehicles where the original strap doesn’t quite reach.
Compatible with most child restraints originally designed with a top tether or hook anchorage — versatile accessory for many seats and capsules.
Simple to install — adds extendable length without complicated modifications, helping you maintain proper safety setup.
Cost-effective solution — avoids the need to buy a new car seat just because of tether length issues.
Essential if you own a large vehicle, wagon, SUV, or van where standard tether straps are often too short or the middle seat has a split.
Useful for parents with multiple cars — keep an extension strap in each car to make seat transfers hassle-free and safe.
Great if you’ve moved cars, changed families, or discovered tether reach problems after purchase — you don’t need to replace your seat.
Ideal for families who value correct installation and safety compliance — ensures the child restraint can be anchored properly.
A smart, low-cost add-on that preserves the use of your existing car seat while adapting it to your car.
