Stewards showed the 21-year-old Monegasque the black and white flag, equivalent to a yellow card in football, after he closed the door on Hamilton as Mercedes's five-times world champion tried to pass.
"He didn't leave me a car's width there, he pushed me off," exclaimed Hamilton over the team radio.
Speaking to reporters later, the runaway championship leader, who finished the race third, said he just wanted consistency from stewards.
"There was a rule put in place, and then it wasn’t abided by today and they used difference consequences for the rule today but I don't really know why that was the case," explained the Briton.
"I guess the stewards woke up on a different side of the bed this morning. I don’t know."
Hamilton nonetheless congratulated Leclerc on a job well done, the 21-year-old polesitter taking his second win for Ferrari in the space of eight days after a first triumph in Belgium.
"I gave him as much pressure as I could and we had a couple of close moments, we could probably talk about it in private together but it’s nothing major and we continue to race," he said. "I’m looking forward to many more races together."
Leclerc had led through the first corner, with Hamilton slotting into second and giving chase.
The two duelled, going wheel to wheel at times, until Hamilton's tyres faded.
Leclerc said he thought he had left enough room but acknowledged also that he had taken a more aggressive approach to his racing since losing out to Red Bull's Max Verstappen in Austria.
In that race, the Dutchman forced Leclerc wide but kept the win after a stewards' enquiry.
"I think since Austria it’s clear that we can go a bit further in the way that we defend and overtake," said the Monegasque.
"I believe that Austria helped me to change this approach and today it’s also thanks to this that I’ve managed to win. It was obviously very on-the-limit but I’m happy to race like this."
