ABSTRACT:
In an exit sign, a cover member for an emergency exit sign has a pair of hook members on its bottom wall and a pair of resilient spring finger members on its top wall. The hook members are dimensionally sized and appropriately positioned to engage catch members on an exit sign housing while the spring finger members resiliently snap fit within spaced apart apertures in the top wall of the exit sign housing thereby retaining the cover member in its closed position. A pair of flexible straps secure the cover member to the exit sign housing to keep them in assembly when the cover member is in its open position.
