Abstract
A bayonet coupling (10) is used for detachable joining of two tubular-shaft instruments or instrument parts. A bayonet sleeve (12) (female part), having a bayonet guide (14), is provided on the one instrument or instrument part, and a bayonet insert (52) (male part) is provided on the other instrument or instrument part. An interlock system serves to lock the bayonet coupling (10) in the closed state. It is proposed that the interlock system have an interlock piece (28), displaceable along the bayonet sleeve (12), which comes directly into inhibiting engagement with the bayonet insert (52) inserted into the bayonet sleeve (12), in the insert's terminal position, and inhibits the bayonet insert (52) from rotating; and which can be moved away from the bayonet insert (52) in order to release the interlock system (FIG. 1).
