A single point separated the sides at the end of a game that the home-side dominated for the most part. But a tally of 15 wides by Clare kept the Shannonsiders hopes alive until the death.
The Banner led by 0-5 to 0-3 at the break and in a tight second period they held out thanks to vital scores by talisman David Tubridy, Gary Brennan and the impressive centre-forward Shane McGrath.
Limerick will rue an early scoring chance when Ian Ryan, from a 20-metre free failed to find the target.
Scorers for Clare: D Tubridy 0-5fs, S McGrath 0-2, Graham Kelly, G Quinlan, G Brennan 0-1 each.
Scorers for Limerick: I Ryan 0-5 (4fs), G Collins 0-2, P Ranahan, S Kelly 0-1 each.
