The housing is glow wire compliant per the series spec, which matters for appliance and lighting applications where the connector sits inside an enclosure subject to flammability testing.
The listing note is unambiguous: contacts are not included.

The polyamide (nylon) insulation material holds up in that band, and the latch lock keeps the connection stable as the harness expands and contracts. The glow wire compliance adds a layer of safety for equipment that must pass IEC 60695-2-11.
