Abstract

A fastener for securing two pipe adapters within a casing such as a gas turbine casing is provided. The fastener comprises a fastener body (25) having a central bore (26) for receiving the pipe adapters and having a first engagement portion (27), e.g. a radial projection extending into said central bore, for engagement with a first pipe adapter (8). The central bore has a second engagement portion, e.g. a threaded portion (39), for engagement with a second pipe adapter (2). The fastener further comprises an outer wall (30) at least partly surrounding and spaced from the fastener body (25) in a concentric arrangement. The outer wall (30) comprises a fastener flange (31) extending radially in a direction away from the fastener body (25) for overlaying the casing (5). At least a portion (32) of the outer wall is deformable (e.g. formed as bellows) so that, in use, axial and/or radial movement of the pipe adapters is dampened.
