A lever mechanism (1) for clamping a panel (3) to a housing has a support block (2) which, in use, is attached to a panel (3). A first lever (4) is pivotally connected to the support block (2), and arranged so that, in use, it can engage with the housing when in a first position and disengage from the housing when in a second position. A second lever (9) is pivotally mounted on the first lever, and arranged to hold the first lever in its first position by engagement with the support block. A spring or springs (8) biases the first lever towards the second position and/or biases the second lever towards the position in which it engages with the support block. The first lever (4) is mounted for translational movement relative to the support block (2) against the action of a further spring (15) to provide, in use, a predetermined clamp load between the panel (3) and housing.
