Chained wild animal (7)

I believe the answer is:

echidna

'animal' is the definition.
(echidna is a kind of animal)

'chained wild' is the wordplay.
'wild' indicates anagramming the letters.
'chained' with letters rearranged gives 'ECHIDNA'.

(Other definitions for echidna that I've seen before include "This insectivore" , "Had nice (anag) -- spiny anteater" , "Insectivorous mammal" , "Creature with spines" , "Toothless type" .)

I've seen this clue in The Independent.
