A tongue assembly (10) includes a metal plate member (34) having a first portion (36) with a buckle latch receiving first opening (42) and a second portion (46) offset from the first portion. The metal plate member (34) has a second opening (60) between the first and second portions (36 and 46) through which seat belt webbing (16) extends. The first portion (36) of the metal plate member (34) is positionable on one side of the belt webbing (16). The second portion (46) of the metal plate member (34) is positionable on the other side of the belt webbing (16). A seat belt webbing cinch bar (130) is attached to the metal plate member (34) and located on the other side of the belt webbing (16). The cinch bar (130) has a first position in which the belt webbing (16) is located between the first portion (36) of the metal plate member (34) and the cinch bar (130). The cinch bar (130) is pivotable to a second position in which the belt webbing (16) partially encircles the cinch bar (130) and is clamped by the cinch bar to block relative movement of the cinch bar and the belt webbing. The cinch bar (130) has a first surface portion (144) which engages the belt webbing (16) and effects pivotal movement of the cinch bar to the second position in response to force applied to the first surface portion by the belt webbing.
