Abstract: A system for connecting a reagent container to a socket. The container has a cap with an outlet comprising a collar having an opening on its side, the collar surrounding a spout with a movable valve. The valve has a tube surrounded by a disk. A plug is centrally arranged within one end of the tube so the outer walls of the spout form-fit with the inner side of the tube and the inner walls of the spout form-fit with the outer side of the plug for closing the spout. The plug is connected to one end of the tube and a socket for accommodating the outlet of the container's cap. The socket comprises at least two movable levers to engage into openings of the collar and a socket gasket on one side for taking up the tube of the valve and tubing on the opposite side to drain liquids.

The air outlet gap is adjacent to a surface that is arched in the direction of the bottom of the extractor hood.

Abstract: The invention relates to a device for detaching a fish hook from an artificial bait. Said device comprises a first arm, a second arm that is displaceably connected to the first arm and a locking element. One of the two arms can be connected by a first end to the artificial bait or the fishing line and comprises means for receiving a fish hook on a second end. In a first relative arrangement, both arms hold the fish hook in the means for receiving a fish hook so that the latter cannot be detached and in a second relative arrangement release said fish hook. In a first position, the locking element retains both arms in their relative arrangement and in a second position permits a displacement of the arms in relation to one another.
