Keeps going to maintain a relative (5,2)

Ross

I believe the answer is:

holds on

'keeps going' is the definition.
(I've seen this before)

'maintain a relative' is the wordplay.
'maintain' becomes 'hold' (synonyms).
'a relative' becomes 'son' (son is a kind of relative).
'hold'+'son'='HOLDS ON'

'to' acts as a link.

(Another definition for holds on that I've seen is " keeps going".)

I've seen this clue in the Evening Standard.
