A tubular clip (1) for securing a sleeve (3) to the body of a piezoelectric actuator (5) in an actuator assembly. In use, the wall of the clip (1) has a plurality of corrugations (7). The pitch of the corrugations is variable in the direction of the longitudinal axis of the clip (1). The clip (1) is configurable into an unfitted configuration and into a fitted configuration and in the fitted configuration the minimum transverse internal separation of the clip walls is less than in the unfitted configuration.
