Device for locking a bayonet closure

A device for arresting a bayonet closure, wherein the device comprises a first connecting partner with at least one coupling protrusion for locking the connection and a second connecting partner with at least one coupling channel, wherein the at least one coupling protrusion and the coupling channel form a bayonet closure, wherein the at least one coupling protrusion can be introduced into the at least one coupling channel via a movement along a longitudinal axis of the second connecting partner and a subsequent rotation in a first circumferential direction about the longitudinal axis, wherein the first connecting partner has at least one first securing partner and the second connecting partner has at least one second securing partner wherein the at least one first securing partner and the at least one second securing partner are designed to arrest a rotation in a second circumferential direction, counter to the first circumferential direction, when the at least one coupling protrusion has been introduced into the at least one coupling channel via the movement along the longitudinal axis and the rotation in the first circumferential direction.
