1. An assembly for a turbomachine turbine comprising:
a casing including an annular wall extending about an axis and at least two attachment bosses extending radially outwardly from the annular wall of the casing, said at least two attachment bosses being circumferentially spaced from each other, and
means of cooling the casing, said means of cooling comprising:
a collector housing comprising at least two upstream attachment areas which are each attached to a corresponding attachment boss of the at least two attachment bosses by upstream means of attachment and at least one downstream attachment area attached to the casing by downstream means of attachment; and
at least one tube extending circumferentially around the annular wall of the casing and connected to the collector housing, the at least one tube having cooling-air ejection orifices,
wherein at least one of the upstream means of attachment or the downstream means of attachment allow relative movement in an axial direction and/or in the circumferential direction between the corresponding attachment area of the collector housing and the corresponding attachment boss or between the corresponding attachment area of the collector housing and the casing, and in that each upstream means of attachment attached to an upstream attachment area comprises an insert mounted in a recess of the attachment boss,
wherein each of the upstream means of attachment comprises a connecting member which connects the upstream attachment area to the corresponding attachment boss, the connecting member being a screw, cooperating with an internal tapping of the insert,
wherein each upstream means of attachment comprises a support member integral with the corresponding attachment boss and the support member comprising a support rim situated radially outside the corresponding upstream attachment area of the collector housing, an elastic member being a compression member mounted radially between the support member and the corresponding upstream attachment area of the collector housing.
