摘要： A buckle assembly formed of a male buckle portion and a female buckle portion. The female buckle portion has a top wall, a bottom wall, side walls, and a cavity between the top wall and the bottom wall and a locking slot in each of the side walls. The male buckle portion has a base, two locking legs, a center leg, and two intermediate legs between the locking legs and the center leg. The locking legs extend through the locking slots in the female portion, and locking pawls at the end of the locking legs engage the edges of the locking slots to secure the buckle portions together. Each locking leg is connected to a flexible retaining member that prevents the locking legs from being flexed outwardly beyond a predetermined point. The intermediate legs and/or the retaining members form stop surfaces that prevent the locking legs from being flexed inwardly beyond a point of contact with the stop surfaces.
