<p>A frameless frame clip is shown in Figure 2 in side elevation, and comprises a pair of limbs 10, 16 to engage on opposite sides of the sandwich together with a tongue 24 struck up out of an extension of the limb 16 and spring loaded towards the limb 10, the two limbs being connected by a bridge portion 40 which is acutely related to the limbs 16, 12. This provides a clip which can be snap-engaged with the assembly of board and cover with generous tolerances to thickness and position of slot to be engaged by the hook 18 at one end of the limb 16.</p> |
