Connectors with adjustable elements to prevent undesired coupling of adjacent conduits

摘要

A connection for ensuring a correct coupling of two conduits including two connectors adapted to be fitted one within the other along an axis of fit and which connectors include initially engageable portions that permit a controlled angular indexing of the two connectors as they are initially brought into engagement and which further include selectively adjustable elements that prevent a complete joining of the connectors if at least one of the adjustable elements of one of the connectors is positioned to block an opposing adjustable element of the other connector.
