A metal obturating element is 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, a portion dimensioned for covering the hole and having an end intended to be inserted into the hole, and a portion for connecting the portion to the peripheral edge, having a surface tilted rearwards relatively to the end and around the portion, this surface intended to be welded to the outer side of the edge of the hole. The element is formed with a deep-drawn part. The tilted surface forms around the central portion an angle greater than or equal to 50° and less than or equal to 80° relatively to the axis. The part includes in a second side located opposite to the first side another surface tilted rearwards relatively to the end and this by at least one angle greater than or equal to 10° and less than or equal to 80° relatively to the axis. |
