Albert Barnes Commentary Judges 4:17

"Howbeit Sisera fled away on his feet to the tent of Jael the wife of Heber the Kenite; for there was peace between Jabin the king of Hazor and the house of Heber the Kenite." — Judges 4:17 (ASV)

Sisera went, not to Heber’s tent, but to Joel’s, as more secure from pursuit. Women occupied a separate tent. (Genesis 18:6, Genesis 18:10; Genesis 24:67).
