SAO PAULO, April 29 (Reuters) - Brazilian retailer CVLB Brasil has filed for bankruptcy protection, saying on Wednesday that it needed to broaden and provide greater legal stability to an ongoing debt restructuring process.

"The company clarifies that its sales ecosystem, which includes physical stores and digital channels, remains fully operational," said the retailer, which runs the CASA&VIDEO and Le Biscuit store chains.
