AbstractA safety belt buckle which permits release of a tongue by the application of minimal pressure on a tongue release member, even under conditions of great stress, yet having strength and reliability. When the tongue is inserted in the buckle it forces a tongue ejecting member back against a biasing force, and an outwardly biased tongue release member moves forward in response to its bias, forcing a detent, such as a roller, into an opening in the tongue. The detent continues to extend into a similar coincident opening in a plate contiguous with the tongue, thus locking the tongue in the buckle. Applying slight pressure to the tongue release member, to slide it back against its bias, provides sufficient space above the opening so that the detent is free to leave the opening in the tongue. The tongue is then ejected from the buckle by the ejector which comes to rest below the opening in the plate, thus retaining the detent out of the path of an inserted tongue.
