In cases where a court permits a defendant convicted of any criminal offense to give bond or confess judgment, with sureties to secure the fine and costs which may be imposed, the acceptance of such security shall be upon the condition that it shall not operate as a discharge of the original judgment against the defendant nor as a discharge of his person from the custody of the law until the fine and costs are paid. (1879, c. 264; Code, s. 749; 1885, c. 364; Rev., s. 1293; C.S., s. 1269; 1971, c. 269, s. 9.)
