Display brand as link

Hello,
I am trying to implement showing brands at product page. Currently I am using following code for this:

$db =& JFactory::getDBO();
      $query = 'select category_name from '.hikashop_table('category').' where category_id = '.$this->element->product_manufacturer_id;
      $db->setQuery($query);
      $brand = $db->loadResult();
if ($brand != NULL) {
      echo '<span class="h_brands">Brand: '.$brand.'</span>';
	}

It was already enabled, but there was an template override for the view used for displaying product and there was no code for displaying brands. I've had a look at original hikashop view file and restored code that was rendering brand. Thank you!
