If you search for "DC female power adapter" you'll get thousands of listings...including variants with wires already attached (instead of screw terminals). Most of these sellers also sell the 12V DC-output wall-warts themselves so the coaxial/barrel plug will match the adapter. If you already have the wall-wart by all means measure it to be sure, but for this low-power application the most common coaxial plug type is 5.5mm x 2.1mm (outside x inside diameter).
