Collins headed over from close range late in the first half
The draw was enough for Ireland to avoid relegation from Nations League B but their failure to win means they will drop into the pot of third seeds for next month’s 2022 World Cup qualifying draw.
Collins told Sky Sports : "We came into the game tonight wanting to win, definitely not lose the game.
"We wanted to win the game and we had the better chances to do that, but we just couldn't break them down.
"But I suppose on a positive note, we haven't been relegated, so that's a bit of good news."
