Abstract
A female element of a threaded tubular connection that is fitted to undergo diametrical expansion in a plastic deformation region. The female element is disposed at one end of a tubular component and includes on its external periphery a mechanism that absorbs scratch energy of a scratching body that may come into external contact with the female element and a mechanism that retains the scratch energy absorption mechanism. The retaining mechanism is configured to prevent release of debris from the scratch energy absorption mechanism during expansion of the threaded tubular connection.
