A child restraint harness system includes first and second shoulder straps that have button holes located on the y-axis of the straps and a chest clip device which consists of two separate connectors that join together to form the chest clip device. On each connector, there is an extension guard located on the inferior portion of the chest clip device. Also, on each extension guard, there is a button located inferior to the bottom shoulder strap slot. Once the first and second shoulder straps are threaded through the top shoulder strap slot and then threaded through the bottom shoulder strap slot, the extension guard located on the inferior portion of the chest clip device can be buttoned into the shoulder straps, which secures the chest clip device in the proper position so the child cannot move the chest clip in the downward position. Once the child grows to the next strap level on the safety seat, the chest clip can be unfastened and each extension on the connector can be unbuttoned and moved up to reach the proper placement of the chest clip on the child.
