Insults mate with false respect (3,7)
I believe the answer is:
lip service
'false respect' is the definition.
'insults mate' is the wordplay.
'insults' becomes 'lip' (informal term for insolence).
'mate' becomes 'service' (servicing is a kind of mating).
'lip'+'service'='LIP-SERVICE'
'with' is the link.
(Other definitions for lip service that I've seen before include "It may be paid" , "The hypocrisy" , "Unreliable support" , "getting no proper acknowledgment" , "Insincere support" .)
