SSIS 2005 remove and/or edit connections from Connection manager

Hi,

I'm using SSIS 2005

When I add a new (OLE DB) connection manager to a package, it prompts for "Configure OLE DB Connection Manager"
and shows al my previously created data connections.

There are 3 things i want to accomplish :

1) remove some old unusable connections from the list

2) rename some of the DB2 data connections because they are now named :                                         

            server.catalog.user
                       server.catalog.user1
                       server.catalog.user2 etc

3) edit the properties of the stored connection

I've searched for remove and rename connection managers, but all I can find is how to remove them from a package, not from the dialog that shows when you add a new one.

If I only could find where these connections are stored . . .

TIA
