Abstract

The device (1) has a locking unit (4) which holds one or more piercing pistons (3) of an energy-­ carrying unit (6) in their locked position. The device comprises a thermofuse arrangement (8, 9, 8) which breaks when a critical temperature is exceeded, and which is supported, at one end, on a longitudinally movable locking rod member (5) which is in operational communication with the piercing piston (3). The individual fuse elements (8, 9) optimize the operational reliability of the device. The fuse elements are arranged in parallel rather than in series in a further embodiment.
