The former Chelsea left back is going to Bramall Lane for his second loan spell, after spending time with The Blades last season.
Harley has penned an initial month long deal, but could stay long term in South Yorkshire.
"We were absolutely delighted to get him," said manager Neil Warnock.
"We were looking for a centre-half but Jon was available and said he was desperate to come back.
'In fact he's asked if he can stay longer than the initial month we have signed him for."
Harley should make his debut in Tuesday derby clash with Rotherham United.
