A tongue plate slidably fitted on a safety seat belt which comprises a continuous webbing which consists of a lap belt and a shoulder belt. A projection or a plurality of projections are provided in a slotted opening formed in the tongue plate, which opening provides for the passage of webbing therethrough whereby abrasion or frictional resistance of the lap belt is to be reduced when the lap belt is moved only in the direction of the shoulder belt. Suitable slack of the shoulder belt can be achieved by making the slack of the lap belt considerably smaller than that of the shoulder belt by means of said reduced frictional resistance of the lap belt.
