Abstract: A disconnection device, in particular for disconnecting two electrically connected electrochemical elements. The present invention also relates to a device for short-circuiting two electrodes of opposite polarity in an electrochemical element. The subject matter of the invention includes an assembly comprising: ⋅ a) a connecting part (3) and ⋅ b) a disconnection device (4), the disconnection device being intended to disconnect two electrochemical elements (1, 2) connected by the connecting part (3), the disconnection device (4) comprising: ⋅ i) microparticles (5) capable of expanding when their temperature reaches a threshold value, the threshold value being below 150° C., ⋅ ii) a capsule (4a, 4b) enclosing all of the microparticles (5), the capsule (4a, 4b) being arranged such that when the temperature of the microparticles (5) reaches the threshold value, the expansion of the microparticles disconnects the connection between the two electrochemical elements (1, 2).

Abstract: There is provided a method for sealing a filling orifice formed on a wall of a container in a leak-proof manner using a stopper arrangement comprising a tubular member with a flange having an upper face, and a lower face for covering the orifice, and a mandrel with a stem which is housed inside the tubular member, the force necessary for rupturing the stem being greater than the force resulting from the entry and advancement of a head of the mandrel inside the tubular member, comprising introducing the stopper arrangement into the orifice, bringing the nosepiece of the riveting tool into abutment with the upper face of the flange, actuating the riveting tool so as to exert a tensile force on the stem and bring about expansion of the tubular member against the wall of the orifice and rupturing the stem of the stopper arrangement.
