The joint is formed in one piece with the parts (1, 2) which are pivotable by means of a thin union part between closed and open positions. In the latter position they form an angle with one another. - The first part (1) has an opening and stop component formed as a hook (10) extending towards the union part, and with a stop at its free end. The second part (2) has a projecting heel formation (11) with an opening (12) through which the hook extends. In the closed position, the hook is bent and tensions the second part towards the open position, whilst the stop locates against the heel formation in the open position, preventing further opening. |
