An improved top-loading stapler having an internal mechanism for temporarily preventing the upper member of the stapler from closing during a loading operation. The improvement consists of an internal U-shaped spring clip that is attached to the upper member. The arms of the spring clip may be biased against the lower member such that the upper member is temporarily held in the open position under the frictional force between the arms of the spring clip and the lower member. The arms of the spring clip may also include inwardly extending detents, such that when the upper member may be positively held in the open position as the detents rest on the top of the lower member.
