This coupling mechanism consists of a twist and snap design featuring interlocking studs and slots. The bayonet connection is most recognisable in its use on BNC connectors. This type of mating mechanism is often chosen when applications require quick connection, with the tactile 'snap' providing positive confirmation.

Connector series featuring this mechanism include: BNC, C, HD-BNC, MHV, SHV, TPS, ZMA, and more.
