US Patent 7758370 Quick release electrical connector

The electrical connector has a tubular sleeve and an outer tubular housing disposed over the tubular sleeve with at least two openings in the outer tubular housing to receive projections from the tubular sleeve. A resilient member biases the tubular sleeve and outer tubular housing relative to one another. Moving the outer tubular housing relative to the tubular sleeve pushes the projections radially inward to release the electrical connector. In an alternative embodiment, moving the outer tubular housing pulls the projections radially outward releasing the electrical connector.
