A safety pressure release locking gas cap is shown. The gas cap is comprised of a handle element, and a plug element. The plug element is rotatably housed in the handle element, and has external threads. A lock element is contained between the handle element and the plug element and can be used to lock the two components together. Locking arises by rotation of the lock element, for example by a key, about an axis of rotation which is a first manner of movement. The lock element has also a second manner of movement, which is axially along the axis of rotation. Movement in the second manner moves a valve from a pressure containing position to a pressure relief position. According to the present invention the movement in the first manner occurs independently from movement in the second manner.
