ABSTRACT:
A closing element intended for closing off an end of a capillary gas chromatography column comprises a closing body provided with a blind hole, which tapers over at least a portion of the length thereof, and the walls of the tapering portion of the hole include an angle with the centerline of the hole, this angle being so small that upon placement of the closing element on the end of the capillary gas chromatography column, a self-locking engagement between the end of the column and the closing element occurs. The closing element is manufactured from a form-retaining, inert, gastight material.
