<p>In many pawl-type fasteners, there is often doubt as to the position of the pawl member since the pawl member is fixed behind the panel and support. Thus, there is provided a fastener (1) which has a screw-threaded stud (2) which passes through a sleeve (3) having at least one axially extending slot (10). A pawl member (4) is screw-threaded on to the stud (2), the pawl member (4) being fixed against rotation relative to the sleeve (3) and having a projection (13) which passes through the axial slot (10) in the sleeve (3). A spring (5) between the head (6) and the pawl member (4) urges the pawl member (4) away from the head (6) of the stud (2), and an abutment (9) on the sleeve (3) engages the sides of an aperture (16, 17) in at least one of a panel (P) and support (S) in use to prevent further rotation of the sleeve (3) relative to the panel (P) and support (S).</p> |
