ABSTRACT:
A mounting particularly for attaching a tubular nozzle shroud member of a gas turbine in co-axial registration with an aperture in a supporting wall comprising a spigot at the end of the tubular member to be fitted into the aperture, the spigot being of complementary shape to the aperture and having radially outwardly extending lugs spaced apart around its periphery, and the wall having a corresponding number of notches spaced apart around the periphery of the aperture, the lugs being aligned with the notches and inserted through the latter by axial movement of the tubular member and retained, in the manner of a bayonet-type of coupling, by the portions of the wall between the notches when the tubular member has been partly turned about its longitudinal axis, the tubular member also having a flange spaced axially from the lugs and sealingly engaged with the wall when the lugs are located behind said wall portions, to hold the tubular member from axial movement with respect to the wall, the wall and the flange each having a pin-receiving opening therein, the openings being so positioned in the wall and the flange that when the tubular member has been turned to the retained position the openings are in registration one with the other and receive a removable locking pin to prevent turning of the tubular member from the retained position, one of the openings being elongate in a direction radially of the longitudinal axis of the tubular member to permit limited relative movement between the tubular member and the wall.
