'sleeve badges' is the definition.
Although both the answer and definition are plural nouns, I cannot see how one could define the other.

'allowed among members' is the wordplay.
'allowed' becomes 'let' (to let is to allow or permit).
'among' means one lot of letters goes inside another.
'members' becomes 'arms' (arm is a kind of member).
'let' going within 'arms' is 'ARMLETS'.
