A bayonet attachment refers to a type of fastening or coupling mechanism characterized by an interlocking design, often cylindrical or polygonal. This design allows for a swift and secure connection, typically employing a twist-and-lock mechanism. In this mechanism, one component is inserted into another, and a twist secures the components together. Bayonet attachments find application in various fields, including camera lens attachments, electrical connectors, lighting fixtures, and specific closures.
