A turbine ring assembly includes adjacent ring sectors forming a turbine ring, each ring sector having a platform with an inner face defining the inner face of the turbine ring and an outer face from which an upstream lug and a downstream lug extend along the radial direction. Each ring sector includes a first groove present in the platform in the vicinity of the inner face of the platform, a second groove present in the platform in the vicinity of the outer face of the platform, an upstream groove extending into the upstream lug and a downstream groove extending into the downstream lug. A first sealing tab extends into the first groove. A second sealing tab extends into the second groove. An upstream sealing tab extends into the upstream groove. A downstream sealing tab extends into the downstream groove. The second sealing tab includes at least one opening.
