The invention relates to a metal obturating element (100), capable of being resistance-welded to the outer side of an edge of a hole of a metal wall of a pressurized gas reservoir of a gas generator, including on a first side (101), a portion (1) dimensioned for covering the hole and having an end (11) intended to be inserted into the hole (T), and a portion (2) for connecting the portion (1) to the peripheral edge (3), having a surface (20) tilted rearwards relatively to the end (11) and around the portion (1), this surface (20) being intended to be welded to the outer side of the edge of the hole. According to the invention, the element (100) is characterized in that it is formed with a deep-drawn part, the tilted surface (20) forms around the central portion (1) an angle (ANG) greater than or equal to 50 degrees and less than or equal to 80 degrees relatively to the axis (10), the part including in a second side (102) located opposite to the first side (101) another surface (4) tilted rearwards relatively to the end (11) and this by at least one angle (ANG2) greater than or equal to 10 degrees and less than or equal to 80 degrees relatively to the axis (10).
