Hide 'Connect To Outlook' button from Calendar Tab Ribbon (SharePoint 2010)

Question

How can I, via a feature, hide the 'Connect To Outlook' button from the 'Connect & Export' group in the 'Calendar' tab when I view a calendar on a SharePoint 2010 site?

I have tried several variations, none of them work. What is the correct XML for this?

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <HideCustomAction
      Location="Ribbon.Calendar.Calendar.Actions"
      HideActionId="ConnectToClient">
    </HideCustomAction>
</Elements>


<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <HideCustomAction
      Location="Ribbon.Calendar.Calendar.Actions"
      HideActionId="Ribbon.Calendar.Calendar.Actions.ConnectToClient">
    </HideCustomAction>
</Elements>


<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <HideCustomAction
      Location="Ribbon.Calendar.Calendar.Actions.Controls"
      HideActionId="Ribbon.Calendar.Calendar.Actions.ConnectToClient">
    </HideCustomAction>
</Elements>

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <HideCustomAction
      Id="RemoveRibbonButton"
      Location="Ribbon.Calendar.Calendar.Actions.ConnectToClient">
    </HideCustomAction>
</Elements>

    <?xml version="1.0" encoding="utf-8"?>
    <Elements xmlns="http://schemas.microsoft.com/sharepoint/">
        <CustomAction
          Id="Remove.Calendar.ConnectToClient"
          Location="CommandUI.Ribbon">
            <CommandUIExtension>
                <CommandUIDefinitions>
                    <CommandUIDefinition

            </CommandUIExtension>
        </CustomAction>
    </Elements>

            </CommandUIExtension>
        </CustomAction>
    </Elements>

According to Connect to Outlook – Tipps und Tricks (English version), it looks like you want something like this:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <CustomAction
      Id="RemoveRibbonButton"
      Location="CommandUI.Ribbon"
      RegistrationType="List"
      RegistrationId="106">
        <CommandUIExtension>
            <CommandUIDefinitions>
                <CommandUIDefinition
                  Location="Ribbon.Calendar.Calendar.Actions.ConnectToClient" />
            </CommandUIDefinitions>
        </CommandUIExtension>
    </CustomAction>
</Elements>
