"Fixture" generally refers to things permanently attached to the structure. A light fixture would be one example, screwed to the wall or ceiling. The light fixture, also called a luminaire, would include devices for holding the lighting elements, supplying electricity to them, enclosing the connections for safety, and means for attaching it to the electrical supply permanently. A "fixture" could, in theory, dangle from a cord permanently attached to a suitable support. For contrast, a cord-connected device would not be a fixture. In fact, it is often illegal to use cord and plug on any appliance that is permanently attached (e.g., screwed in or with water pipes attached).
