Hide from a glutton's relations (7)
I believe the answer is:
pigskin
'hide' is the definition.
(thesaurus)
'a glutton's relations' is the wordplay.
'a glutton's' becomes 'pigs' (I've seen this in other clues).
'relations' becomes 'kin' (both can mean one's family).
'pigs'+'kin'='PIGSKIN'
'from' is the link.
(Other definitions for pigskin that I've seen before include "Football material" , "Strong leather - (American) football" , "Type of leather" .)
