WooCommerce: How to add custom text between variation title (label) and dropdown selector

Question

We would like to add (fixed) custom text in between the title/label of the product variation and the dropdown selector like indicated below.

We already tried following code

add_filter( 'woocommerce_attribute_label', 'custom_attribute_label', 10, 3 );
function custom_attribute_label( $label, $name, $product ) {
    $taxonomy = 'pa_'.$name;

    if( $taxonomy == 'pa_bodenankertyp' )
        $label .= '<div class="custom-label">' . __('MY custom TEXT', 'woocommerce') . '</div>';

    return $label;
}

from this post Adding a custom text next to a specific product attribute label in WooCommerce

but it does not work.

Any idea or hints what is wrong are appreciated!

I would not recommend using this hook since you change it in multiple places - places where you don't want any changes. I would suggest overwriting the specific WooCommerce template. For that, go to your child theme and create the following folder structure:

your-child-theme/woocommerce/single-product/add-to-cart/

Now you need to create a PHP file named variable.php in there and paste the following code inside:

<?php
/**
 * Variable product add to cart
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/add-to-cart/variable.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce\Templates
 * @version 3.5.5

global $product;

$attribute_keys  = array_keys( $attributes );
$variations_json = wp_json_encode( $available_variations );
$variations_attr = function_exists( 'wc_esc_json' ) ? wc_esc_json( $variations_json ) : _wp_specialchars( $variations_json, ENT_QUOTES, 'UTF-8', true );

                                );

                    </tr>
                <?php endforeach; ?>
            </tbody>
        </table>

        <div class="single_variation_wrap">
            <?php
                /**

                /**

                 */
                do_action( 'woocommerce_single_variation' );

                /**
                 * Hook: woocommerce_after_single_variation.
                 */
                do_action( 'woocommerce_after_single_variation' );
            ?>
        </div>
    <?php endif; ?>

    <?php do_action( 'woocommerce_after_variations_form' ); ?>
</form>

<?php
do_action( 'woocommerce_after_add_to_cart_form' );

In this code you will find your div. If you need any checks, just put them around your div. In your case I would check the variable $attribute_name.
