<p>The invention relates to a closing element for sealing holes subjected to internal pressure, comprising a hollow cylindrical main body (3) that can be inserted into the hole substantially without play, and a hat-like spreading element (8) that can be pressed into the main body, wherein said spreading element applies radial pressure to the inner wall of the main body (3) in the installed state, wherein the main body is spread and pressed against the wall of the hole to be closed. The main body (3) has a closing bottom (5), which has a circumferential radial ring surface (6) and a slightly conical cone surface (7) connected thereto, wherein during operation the closing bottom is pressed against the end face (12) of the spreading element (8) by the internal pressure and is bent over the inner and outer edge of the end face and deformed so as to expand radially. This results in strengthened anchoring of the closure in the material of the component, wherein at the same time a self-reinforcement of the press-out force required to remove the closure is caused.</p> |
