A one-hand operated strap buckle capable of withstanding high forces and yet simple to operate and easily connected to a post and disconnected from a post. In a preferred embodiment, the buckle comprises upper and lower cases, the latter forming a slot for receiving a post with a flat head. When connected to a post, the buckle is secured to the post by a pair of swing arms terminating at locking hooks. The position of the swing arms is normally closed, but may be readily altered to an open position by a pair of opposed spring-loaded release tabs which when compressed toward one another, open the swing arms and separate the locking hooks. The buckle of the invention also comprises a strap release which is spring-loaded and normally engages the teeth of a strap by employing a spring-loaded catch which can be rotated away from the strap with tilting of the strap release around a fulcrum bearing. The locking hooks of the preferred embodiment, when in their locked position, assure a secure connection to the post which connection can withstand very high forces.
