1. A method for manufacturing a housing enclosing a pyrotechnic charge, said method comprising at least:
inserting a pyrotechnic charge into a charging volume laterally delimited by a rigid cylindrical charging wall and in a lower part by a first element of a housing to be obtained,
positioning a second element of the housing to be obtained above the inserted pyrotechnic charge and in an extension of the cylindrical charging wall, said second element having a lateral cylindrical wall of the same shape and diameter as the cylindrical charging wall and being able to cooperate with the first element, and
jointly translating the second element and the cylindrical charging wall relative to the first element so as to make the second element cooperate with the first element and form the housing enclosing the pyrotechnic charge.
