A tongue assembly for use in a safety apparatus in which belt webbing restrains movement of an occupant of a vehicle or of a child seat includes a metal base. The base has a passage through which the belt webbing extends. A plastic cover is fixed to the base and has a belt clamping portion. The tongue assembly also includes a slide bar around which the belt webbing extends. The slide bar is movable relative to the base and cover between a first position in which the slide bar clamps the belt webbing against the belt clamping portion of the cover to block movement of the belt webbing through the passage and a second position in which the belt webbing is movable through the passage.
