A tilt drum for securing the upper ends of the side cords of a cord-type ladder to a venetian blind tilt rod for operation thereby. The tilt drum is formed with a one-piece body of synthetic resin material and includes a drum section adapted for mounting on the tilt rod and a cover section integrally connected by a flexible hinge portion to the drum section. The drum section has a top wall overlying the tilt rod and interfitting ribs are provided on the cover section and the top wall of the drum section for clamping end portions of the side cords of the ladder tape to the drum section, when the cover section is closed. A latch is formed integrally with the cover section and arranged to engage a keeper on the drum section to latch the cover section in a closed position.
