The league’s 11th and 12th-placed sides met at the Nelson Mandela Bay Stadium, looking for positive results.
It was a six-pointer and all to play for with both sides tied on five points and knew a win would take either of them into the top eight.
After a disappointing start, the game sprung to life after 38 minutes when James Okwuosa was unfortunate to see his header come off the post.
Chances were few and far between for both sides, with either of them reduced to half-hearted attempts that did little to pose any threat to their respective keepers.
While Celtic looked promising going forward, they failed to provide anything concrete on goal as the opening half ended goalless.
Siwelele started with a bit more urgency in the second half and came close to scoring when Daniel Akpeyi stopped Tshegofatso Mabasa’s effort.
The introduction of Ruggert Nyundu added firepower upfront, but they still found it difficult to effectively break down the Chilli Boys defence.
Chippa were once again denied by the post through substitute Lerato Manzini eight minutes from time.
Manzini was in on goal again minutes later, but was this time he was denied by Patrick Tignyemb.
It ended all square with both sides remaining in their respective positions on the PSL log.
