<p>A fixing device comprises a sleeve portion (10) and an engagement portion (13) which are spaced apart but which are interconnected by two flexible strut members (15), each of which includes short and long arms (16, 17). A screw (12) can be inserted through a central hole (11) in the sleeve portion (10) so that its end engages in a hole (14) in the engagement portion (13): this serves initially to hold the portion (13) in a fixed position relative to the portion (10) and thereby resist flexing movement of the strut members (15). Upon subsequent tightening of the screw, the portions (10) and (13) are caused to move together, thereby flexing the members (15) outwardly.</p> |
