This works with all standard car seat belts, and all brands of child car seats. YOU MUST HAVE THIS if you own an older car and have a lap/shoulder belt-mounted child car seat or car seat base! YOU DO NOT NEED THIS if you use the LATCH mounting system. In most older cars, with a combination lap/shoulder belt, regardless of what kind of retractor or locking mechanism the vehicle has, if you don't use a locking clip (or if you have one and attach it to the wrong part of the belt, as I did until someone explained it) and you have an accident--or even just brake hard or turn to try to avoid an accident--your car seat or car seat base will likely pull the slack out of the lap portion of the belt and will get additional slack from the belt that goes up to the shoulder mount. What this looks like is the seat tilts away from the side where the shoulder belt anchor is, and toward the front of the vehicle, producing a twisting motion which is dangerous to the child's back and neck. What you want is (assuming your car seat or base is already strapped in securely first) to lock the shoulder belt to the seat belt BETWEEN THE TWO LAP ANCHORS, rendering the shoulder part of the belt irrelevant, which also keeps that dangerous slack away from the lap belt. This is the best and simplest design for this clip...just a flat piece of metal cut in a shape that allows the middle of two flat webbing straps (seat belts, in this case) to be slid in from one side, with both belts getting tucked under the "ears" that stick out at both ends, and the middle bar staying on the other side of the belts. Most car seats are supplied with one of these (look underneath or on the back of the seat for the place where one would be stored when not in use). IF YOU DID NOT GET ONE OF THESE WITH YOUR CAR SEAT OR CAR SEAT BASE, THIS COULD BE THE BEST PURCHASE YOU EVER MADE. ** Also consider the Graco model sold on Amazon, nearly identical for less money.

Editorial Review

Securing your baby's car seat inside your vehicle is critical for safety reasons. The Evenflo Seat Belt Locking Clip gives you the assurance of knowing your baby's seat is correctly positioned, through its sliding latch plates. Locking clips are inexpensive and underused, yet they could save your child's life. With many types of vehicles, locking clips are an essential aspect of in-car child safety, because without them it's often difficult to install a car seat tightly enough.
