comments_where Hook

is there a similar replacement of the hook posts_where for comments?
I need to modify the where clause for a comments query like it is shown in this tutorial (“4. Sub custom field values”) for posts.
The only hook I found is comments_pre_query, but the property $query->meta_query_clauses[ 'where' ] is protected.
