Abstract: A locking system is described for detachably securing two workpieces together (e.g., two housing sections). Elongated arms (12, 14) are carried by one workpiece (40) and a corresponding opening(s) is present in the other workpiece (50). The outer end of each elongated arm is resiliently deflectable so that it is deflected when being inserted into the opening in the one workpiece; then the arm springs back. A locking arm on the second workpiece is then able to move behind the end of the elongated arm to restrict deflection of the arm, thus prevent­ing any unintentional unlocking of the two workpieces.
