Abstract A safety fastener for a two-section container having an integral slide which is selectively engaged with a portion of one or both sections of the container to permit the container to be opened or to be maintained in a locked position. The slide has a resilient portion which upon being depressed permits movement of the slide from a locked position to a free position thereby allowing the container to be opened.
