Abstract: Seal (3) comprising at least two deformable shells (1,1?), each one of the shells containing a component and comprising a membrane, characterized in that bringing the component contained in one shell (1) into contact with the component contained in another shell (1?) causes the mixture of the components to crosslink. Use of the seal for wedging electrochemical generators in position in a battery, particularly lithium generators.
