Catches and holds tightly (6)
I believe the answer is:
clasps
I believe this is a double definition.
'catches' is the first definition.
(clasp can mean to clutch or catch)
'holds tightly' is the second definition.
(I've seen this in another clue)
'and' acts as a link.
(Other definitions for clasps that I've seen before include "Necklace fasteners" , "Fasteners, as on necklaces perhaps" , "Embraces; fastenings" , "Holds tightly" , "Holds the fastenings to one's bosom" .)
