Abstract: A cap for closing an open end of a duct tube has a cylindrical side wall having a length between a closed end and an open end of the side wall. An end wall extends across the closed end of the side wall. A conical section of the side wall extends outwardly from the open end of the side wall and has an interior surface configured to guide an end of a duct tube into a hollow interior volume of the side wall. A groove in an interior surface of the side wall is configured to receive a bead around an end of a duct tube inserted through the conical section and into the hollow interior of the side wall. A plurality of pull tabs extend outwardly from the conical section and are configured to be manually pulled, pulling the cap over the end of the duct tube.
