A retaining device for coupling a cover to a sewing machine. A stop is fixed in the base. A lever has a middle portion pivotally supported on a support which is fixed on a bottom of the cover. A handle is formed on one end of the lever and is reachable from outside of the cover. A pawl is formed on the other end of the lever. A spring is provided to bias the pawl to engage with the stop so that the cover can be retained in a closed position. When the handle is pulled upward, the pawl can be separated from the stop so that the cover can be opened.
