Conn. Gen. Stat. § 52-297: Avails of attachment sale may be attached.

After the money accruing from the sale of the property attached has been paid to the clerk of the court, any creditor may attach it by leaving a copy of his attachment, with an endorsement of the service thereon, with such clerk, and a like copy with the defendant, if within this state; in which case the sum which such creditor recovers shall be paid to him, under the order of the court, out of the surplus left after deducting all previous attachments, in the same manner as if he had attached such property before the sale.
