Lockie is a seatbelt positioning device designed to be extremely easy to use. It is used in conjunction with a harnessed car seat and vehicle seatbelt to prevent the seatbelt installation from loosening over time. Lockie is much easier to use than other kinds of seatbelt locking clamps, clips and buckles. Lockie was invented, designed and made in Australia, and was awarded the 2017 Australian Good Design Award.
