A tensioning device used to improve the retention of a child seat after its installation in an auto seat using its installed seat belts. After the child seat is placed on the auto seat and the auto seat belt is engaged about the child seat in a desired manner, the device increases tension in the auto seat belt to improve retention of the child seat. The device uses an open-end slotted and rotatable spool around which the auto seat belt is wrapped. Lever means connect with rotating and locking means, which in turn connect to the rotatable spool to wind the spool in a direction such that would result in effectively shortening of the automobile seat belt.
