What do the Italians call the ‘at’ mark, “@“, sometimes referred to in English as the “ampersat”?

In Italian, the @ sign is called the “chiocciola” ('snail') or more often the “chiocciolina” (‘small snail’).

The "at" sign, @, is normally read aloud as "at" and is referred to as the "at symbol" or "commercial at". There are many disputed theories about the origin of the symbol, which has come to acquire many applications, as a shorthand notation in accountancy, in units of weight, in merchant trade, in computer programming languages, in scientific and technical literature and in some written language applications.

Without doubt, however, the “@” is most often seen today in email addresses and social media platforms. In many languages other than English, although most typewriters included the symbol, the use of @ was less common before email became widespread in the mid-1990s. Consequently, it is often perceived in many languages as denoting "the Internet", computerization, or modernization in general.

The absence of a single English word for the symbol has prompted several suggestions for one but none of these has achieved wide use. Other countries have not been so slow in coming up with figurative names for the symbol. While the Italians refer to the snail or little snail “chiocciola” or “chiocciolina”, the Dutch and South Africans use monkey’s tail (“apenstaart"), the Swedes use cinnamon roll (“kanelbulle”) and the Czechs see the sign like a rolled pickled herring (“zavináč”).
