Car Seat Chest Clip – Anti‑Escape Safety Accessory

Keep your child’s car seat harness properly positioned with this anti‑escape chest clip, designed to prevent toddlers from loosening or slipping out of the shoulder straps during travel.
The model consists of two parts: a base with a central hole and a top piece with a locking insert. Once attached, the clip keeps the straps parallel and stable, improving both comfort and safety.
