Abstract

Abstract A failure safe buckle in which a lug of a male buckle part is captured in a recess of a female buckle part by a latch slide, the latch slide being releasably locked in a position overlying the recess and engaged with the lug. Such a buckle in which the lock mechanism includes relatively movable parts biased to locking positions to lock the latch slide against movement, the relatively movable parts requiring simultaneous opposite movement to permit shifting of the latch slide to a position releasing the lug.
