Device comprises an oblong connection piece (22) that can be adjusted and connects a cover (10) to a container or tank. Integral with the connection piece are sensors (36, 38) for measuring the tension force exerted on the connection piece. A comparator (42) compares the tension force with a pre-set threshold which corresponds to a certain pressure and generates a signal if the force is above the threshold indicating an effective seal. |
