Abstract
System and method for assembling blow molded parts without the use of separate fasteners, including a tab-and-slot or dovetail mortise and tenon joint that includes a slide-and-lock tab feature. A retention barb on the tab slides along a ramp to engage with a receptacle within the slot. Tabs and slots can have varying widths to create mutual incompatibility with other joint components that are otherwise similarly constructed. An optional stopper on the tab and corresponding notch within the slot can add an additional axis of incompatibility with other joints throughout the assembly. These features prevent incorrect assembly and allow convenient redesigns.
