Quick snap with shut-off piece

The quick snap is placed on the shut-off piece so that the two snap levers with spring return engage in the groove of the shut-off piece. Thus a safe connecting is produced without restricting the material flow. When the injection procedure has been finished, the backflow of the material is blocked with the shut-off slide in the shut-off piece and the connection with the quick snap is released by actuating the snap levers. The connecting system can be used for the connection filling hose/injection hose as well as packer/injection hose.
