The Rubber Hose
The rubber hose is a stage prop that reminds the audience of Willy’s desperate attempts at suicide. He has apparently attempted to kill himself by inhaling gas, which is, ironically, the very substance essential to one of the most basic elements with which he must equip his home for his family’s health and comfort—heat. Literal death by inhaling gas parallels the metaphorical death that Willy feels in his struggle to afford such a basic necessity.
