Gov. M. Jodi Rell and Consumer Protection Commissioner Jerry Farrell said on Monday that they have secured the deal to curb the distribution of Four Loko and two similar beverages, including Four Maxed and Joose.
The popular drinks have been banned in Washington, Michigan, Utah and Oklahoma.
Four Loko is made by Chicago-based Phusion Projects. The firm says it is dissapointed by developments in Connecticut and that it was not consulted over the agreement.
College students have been hospitalized after drinking the beverages, including in New Jersey, where one school banned them on campus.
The federal Food and Drug Administration is reviewing the products' safety.
