Abstract: A guard for an electrical receptacle uses a rotating cover to mask the slots in the receptacle. Catch pins engage the cover and hold it in its closed position. Springs means, or similar, automatically return the cover to the closed position.

Abstract: The present invention relates to a tethered protective cover which is detachably mounted to a multi-pin electrical connector. Specifically, the cover is mounted to a diagnostic connector located under the instrument panel of an automobile. The cover includes a shroud which is mountable to the connector. The shroud includes opposite side walls and an intermediate wall extending therebetween. The shroud has a size and shape such that clearances are created between each shroud side wall and the connector. The shroud is formed using a resilient material such that when the opposite side walls are squeezed inwardly, the clearances are reduced, causing the intermediate wall to gap outwardly from the connector. A latch button on the intermediate shroud wall interacts with a projection on the connector to secure the shroud to the connector.
