Permit, stub (6)
I believe the answer is:
ticket
I believe this is a double definition.
'permit' is the first definition.
(I've seen this before)
'stub' is the second definition.

(Other definitions for ticket that I've seen before include "Permit, coupon" , "Voucher, pass" , "'Just the ------': an appropriate thing" , "lottery entry" , "Travel warrant" .)
