Beschreibung
Zusammenfassung:	The invention relates to a device (2) for cooling a turbine casing, preferably of a low-pressure turbine of a turbomachine, with air jets, the device comprising a pressurised air supply housing (3) and at least two curved cooling pipes (40) arranged on either side of the housing (3), around and spaced apart from a part of the casing and provided with air injection holes (41), the housing comprising, in particular, a bottom (31) and two longitudinal side walls (32, 33), and the bottom being pierced by air injection holes. The device is characterised in that each of the side walls extends outwards as at least one single-piece tubular sleeve, to which a cooling pipe is joined, the bottom of the sleeve being located at the same level as the bottom of the housing at the point where they are joined together.
