The Advertising Standards Authority has clashed with the clearance body for TV commercials over its ban of a controversial Tango commercial.
It was feared that children would mimic the advert
The ASA has banned the advert, which shows a young man wrapped in a carpet filled with oranges rolling down a hill and hitting a tree, after complaints.
It feared children could copy the commercial and harm themselves.
But the Broadcast Advertising Clearance Centre said it "strongly disagreed" that it could lead to accidents.
The advert culminates in the man crashing into a tree before being hit by concrete pipes, which cause the oranges to explode.
The disagreement comes less than a month after the ASA took control for regulating broadcast advertising where previously it covered non-broadcast only.
The ASA investigation, published on Wednesday, upholds four complaints from members of the public about the commercial, including ones from the relatives of a boy who was killed in an accident while playing with concrete pipes.
But the BACC, which gave the advert an "ex-kids" restriction preventing it from being shown during children's programmes, disagreed.
It said it was "surreal" by its nature because it featured a man wrapped in a carpet filled with oranges.
The advert was not set on a building site "or in any realistic setting that would suggest that the stunt was able to be copied or would normalise or condone
the behaviour", it said.
Tango adverts are known for their bizarre style and have caused controversy in the past.
But the ASA said the latest commercial differed in a number of ways.
"Previous advertisements included scenes that would be far more difficult to copy, they required equipment that was not readily available or accessible and children were unlikely to perceive the scenarios as at all realistic," it
It decided the commercial was likely to appeal to children and therefore posed a "serious and realistic risk of harm".
Britvic Soft Drinks, which makes Tango, has already apologised for any offence caused by the advert and promised not to show it again.
Previous Tango commercials have also attracted criticism.
Four years ago an advertisement showing a group of orange-haired men reducing an overweight youth to tears by shouting at him through a megaphone was criticised by the Independent Television Commission.
It ruled that the commercial, which was suspended, could have encouraged bullying.
