The device has a mechanism for displacing a sealing profile (30) during operation of the mechanism and comprising a trigger (40) displaceably supported in a longitudinal direction of the device for triggering the operation of the mechanism. The trigger has a spiral spring (60) e.g. plate spring and flexibly bendable wire, comprising a displaceable end indirectly connected with the trigger. The sealing profile is indirectly attached at the spring. The mechanism has a limiting unit (120) e.g. rod, wire, chain, rope and tape, for limiting movement of the profile in its longitudinal direction. |
