Solution 1

Try:

^\d+[-_~]\d+$

Which accepts hyphen, underscore, and tilde as the "special characters" - change that for the ones you need to accept

Solution 2

^\d\-\d$

\d is for digits (numbers)
\- is for - (hyphen)

I think you can get the information you need here: Regular Expressions info[^]

When it comes to characters that are defined with a special meaning, you need to escape them with a backslash (\).

Example:

[0-9\-]+
or
[0-9]+\-[0-9]+

Remember to escape once more if you your language require that.
