The Retainer Clip Guard for Spirit APS Car Seat covers the Retainer Clip only that lays across the chest. It has not been found to be effective on other types of car seats. Removal is slightly more difficult because it is designed to be childproof. To remove the Retainer Clip Guard , "lift-and-twist" the lid in a similar manner that you would open prescription medicine bottles. This helps children stay securely restrained until an adult chooses to remove the child from the car seat.
