Sheath of connective tissue (6)

I believe the answer is:

fascia

'sheath of connective tissue' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for fascia that I've seen before include "Signboard above a shop" , "Detachable (mobile phone) front cover" , "Surface over shop window" , "panel" , "board above shop window" .)

I've seen this clue in The New York Times.
