Neil Lennon's side are heavy favourites to complete the domestic double by adding the famous old trophy to their second successive Clydesdale Bank Premier League championship.
The former Celtic and Hibs midfielder, who won the League Cup in 2007 as Hibees manager, insists Pat Fenlon has to get his players in the right frame of mind and should look at Wigan's attitude in their shock 1-0 FA Cup final win over Manchester City.
"It is a difficult task for Hibs because Celtic are a very good team with lots of good players," Collins said. "It is important the Hibs players go on to the park with no fear. Fear is a terrible thing on a football pitch. It can freeze up your body and mind.
"So you have to make the players believe they are on that pitch as equals of Celtic. Hibs are underdogs but Wigan are a great example for them. The mindset of the Wigan players was sensational and that came from their manager.
"They went up against a great team of individuals in Manchester City but their game plan was to dominate Manchester City when they had the ball and make them chase it, which Manchester City don't like.
"If Hibs have that same mindset against Celtic then they have a chance. Hibs have got to be brave, compact and have to press as a team. They have to make passes with every player wanting the ball and nobody hiding."
Hibs have not won the Scottish Cup in 111 years and will return to the national stadium desperate to make amends for last season's 5-1 drubbing in the final by Edinburgh neighbours Hearts.
