Abstract
A device for releasably locking an item in a panel aperture has a bridge on which are carried two wings each with a first edge nearer the bridge and a second edge more remote from the bridge, the first edges being spaced by less than at least part of the second edges. The second edge is an inclined edge, and the unconstrained spacing of the remoter ends of such edges is greater than the width of the panel aperture. When the item is introduced through the panel aperture, with the bridge leading and the wings trailing, a point of contact between the wings and the panel aperture moves onto the second edge, and inherent resilience of the device prevents return movement of the item through the panel aperture.
