I am trying to separate the two parts of the Samsung tab 2 7.0 AC adapter, since I am traveling to a country with different outlets.
I have tried pulling them but nothing seems to work.
Do you know how they can be separated?
The Samsung Power Supply Unit (PSU) I have (same for: Tab2 7.0, Tab2 10.1, and S3 Mini) just requires a firm pressure, to remove the Australia/New Zealand angle-prong portion.
Push the power-prong element away from the bottom (with CE notice) of PSU. There is no release or catch, to stop this action.
(If this does not exactly match shape/appearance of your PSU, then disregard.)
The alternative approach is to instead obtain a Samsung 30-PIN to micro-USB adapter. This allows you to use ANY standard phone PSU or PC (USB to micro-USB cable) to re-charge the battery.
