Meaning
The fetter of sorrow; grief conceived as a chain that binds the soul.
Literally: shackle of grief
How Iqbal uses it
The companion-image to the prison of life; only death is thought to loose this bond, so the two are released by the same hand.
See it in the verse

Kabhi chhodi hui manzil bhi yaad aati hai rahi ko
Khatak si hai jo sine mein gham-e-manzil na ban jae
Khatak si hai jo sine mein gham-e-manzil na ban jae
