What is a locking clip? Do I need one?
Some vehicle lap and shoulder belts pull and retract freely, with no locking mechanism. A locking-clip allows you to clip together the lap and shoulder portions of a seatbelt, and helps prevent the seat belt from becoming loose before a crash. This will fix the lapbelt at one length to hold a carseat. The locking clip is always installed on the side of the carseat near the buckle, no more than one inch away. If the locking clip is on the wrong side, it can actually cause more slack during a crash, and the forces can cause it to bend or fly off (also a serious hazard!). Consult your carseat or vehicle owner’s manual for details. If your vehicle has locking seatbelts, you usually do not need a locking clip. One exception is for a rear-facing carseat, where a locking clip may be used to prevent a severe tilt in the carseat.A regular locking clip is not load bearing and cannot withstand crash forces.
