The garnishee against whom judgment has been rendered is entitled to a certificate from the clerk stating the date and amount of the garnishment judgment, in whose favor and in what case rendered. Such certificate shall have all the force and effect of a receipt against the original debt, and entitle the garnishee to a credit to the amount thereof on the original judgment, or on the execution if already issued, to be entered by the officer.
