You can use reflection to disable the private bReadOnly field (bad idea, etc.):

typeof(ConfigurationElementCollection)
    .GetField("bReadOnly", BindingFlags.Instance | BindingFlags.NonPublic)
    .SetValue(ConfigurationManager.ConnectionStrings, false);
ConfigurationManager.ConnectionStrings.Add(new ConnectionStringSettings());

This is similar to the technique required to modify an existing connection string, and added as a comment there by Brian Rodgers.
