Abstract: An article for attaching an item to a wheeled suitcase includes a flexible member or strap with one end removably attached to a handle of the suitcase and the other end carrying a collapsible hook, suspended from the handle for holding an auxiliary item such as a briefcase. Attachment at the handle includes a plug and socket that permit rotation relative to the handle without risking disengagement of the plug from the socket when tension on the strap pulls the plug downwardly. The hook has two interlinked members and is secured to the flexible member such that the hook opens when suspended due to tension from the hook's own weight.
