A disassemblable gas-tight and pressure-resistant electrical lead-out for battery cells, consisting of a metallic fixed outer sleeve, a metallic bolt effecting the current conduction and of an insulating piece disposed between the sleeve and the bolt that consists of three sleeve-shaped insulating members disposed axially one behind the other and filling out the interstice between bolt and sleeve; the center insulating member consists of a practically gas-tight deformable material while the two outer members consist of a non-deformable material and at least one of the two outer members is adapted to be axially tightened with respect to the center member; the two outer members are provided on their side facing the center member with a ring-shaped raised portion which penetrates into the center member during axial tightening.

A disassemblable gas-tight and pressure-resistant electrical lead-out for battery cells, comprising a substantially rigid metallic external sleeve means, a metallic bolt means effecting current conduction and insulating means disposed between the sleeve means and the bolt means and including three sleeve-shaped insulating members disposed axially one behind the other and substantially filling out the space between the bolt and sleeve means, the center insulating member being made of a practically gas-tight deformable material while the two outer insulating members are made from a substantially form-stable material, and at least one of the two outer insulating members being adapted to be axially tightened with respect to the center insulating member, characterized in that the two outer insulating members are provided on their sides facing the center member with a ring-shaped raised portion which during axial tightening penetrates in the center insulating member.
