An assembly includes a piece to be held in a bore and a device in which the piece is inserted for holding the piece in the bore. The device comprises a cylindrical sleeve having a series of fins extending longitudinally of an inner surface of the sleeve and projecting inwardly from the inner surface. The fins are skewed in a same circumferential direction relative to radial planes of the sleeve. The sleeve and the fins are integrally formed of resilient flexible plastic. The flexibility of the fins is such that the fins can be readily deflected when engaged by an inserted piece. The device can be used as part of a combination that includes a body having a bore therein, and can be used in a method of holding a piece in a bore of a body.
