The Canaries head to bottom club QPR on Saturday some seven points clear of the drop zone, but without a league win since December 15.
Argentinian forward Becchio - who scored 19 goals for Leeds this season and arrived as part of a swap deal for Wales international Steve Morison - will provide much-needed back-up for captain Grant Holt, and could well be used as an impact player from the bench.
"Becchio is a player in good form this season, which is important," Hughton told a press conference.
"You want someone who is going to hit the ground running and give us something, whether it is starting or on the bench."
Norwich also moved to bring in Kei Kamara on loan from Major League Soccer club Sporting Kansas City, but the Sierra Leone forward is still waiting for international clearance and will not feature this weekend.
Hughton confirmed the Canaries had tabled several "substantial bids" for Celtic frontman Gary Hooper, all of which were rebuffed by the Scottish Premier League side, who are said to have slapped a £10million price-tag on their prized-asset.
"We did put bids in and they were substantial bids, certainly by the levels of this football club," said Hughton.
"All the conversations we had with Celtic were good, amicable conversations, but it was very clear he is a player who they had a big valuation of and did not want to lose."
