ABSTRACT:
An improved access port cover latching assembly is provided with an interlock that normally requires the presence of a component within the access port. A first pin encounters the component and, when displaced, releases a second pin to slide, thereby allowing a latching assembly to seat fully, thereby securing the cover. An independent signalling device may be provided to indicate the absence of the component in the event that the interlock is intentionally defeated to enable latching of the cover.
