Please note that Google Announced: Support for the Android Developer Tools (ADT) in Eclipse has ended, so consider migration to Android Studio.

Solution:

The fastest installation way I found to solve that without deleting eclipse, or losing any data/settings:

1. Go here download latest version of ADT, current ADT-23.0.7.zip (*)
2. At Eclipse > Help > Install new software... > Uncheck Contact all update sites during install to find required software (bottom, last preference) in order to avoid any unwanted delays during install.
3. Same screen (top) Click Add > Archive > select downloaded ADT-X.X.X.zip > follow on screen installation steps

As a user mentioned in a comment if you still face problems on updating like that you may try removing the previous version of ADT before installation.

(*) Previous versions:

• ADT-23.0.0.zip | ADT-23.0.2.zip | ADT-23.0.3.zip | ADT-23.0.4.zip | ADT-23.0.6.zip
• ADT-22.6.0.zip | ADT-22.6.1.zip | ADT-22.6.2.zip | ADT-22.6.3.zip
• ADT-22.3.0.zip
• ADT-22.2.1.zip
• ADT-22.0.0.zip | ADT-22.0.1.zip | ADT-22.0.5.zip

Edit to fit the updates of ADT, this solution seems to work in any version :D
