Display "from" and "to" texts in price range

Hello,

On the product listing page, I have enabled the price range display and that works OK in the sense that the minimum and maximum price are displayed for the respective products.

However, I would like to display it more clearly for my customers. So instead of displaying:
€10 €30 , which I think is a bit vague
I would like to display
from €10 to €30

Using "inspect element" I see it is to be changed somewhere around hikashop_product_price hikashop_product_price_0 and hikashop_product_price hikashop_product_price_1 but could you please indicate more specifically in which PHP file I would need to add which code ?

Many thanks in advance
Ron
