Locking Device for Connecting Two Assemblies

A locking device for connecting two assemblies to one another, comprising:

• a first locking part which is associated with a first one of the assemblies and comprises a housing part and two slots each having at least one first engagement protrusion, wherein at least one of the slots comprises an adjustment element which can be adjusted relative to the housing part, and
• a second locking part which is associated with a second one of the assemblies and comprises two engagement elements each having at least one second engagement protrusion,
• wherein, for closing the locking device, each of the engagement elements of the second locking part can be attached to one of the slots of the first locking part, the first engagement protrusions are engaged with the second engagement protrusions in a closed position for holding the first locking part and the second locking part against one another against the closing direction, and the first locking part and the second locking part can be separated from one another for opening the locking device, wherein the first locking part and the second locking part are movable relative to one another along a movement plane perpendicular to the closing direction for opening the locking device,
• wherein the adjustment element is arranged on the housing part of the first locking part so as to be adjustable between a first position and a second position, wherein, in the first position, the adjustment element is configured to enable the first locking part and the second locking part to be attached to one another along a closing direction for closing the locking device and, in the second position, to block movement of the first locking part and the second locking part along the movement plane relative to one another and thereby blocking an opening of the locking device.
