The clips connect onto the existing harness straps and hold them firmly in position preventing your child from wriggling out.
The Houdini Stop has been officially crashed tested & reviewed by ACRI. The Houdini Stop is legally allowed to be purchased as an aftermarket accessory, and used on a wide range of harnesses.
