A connector assembly includes a first component having a slot and an indentation and a second component having a hook and a protrusion. The hook is configured to engage with the slot by being inserted into the slot and being translated with respect to the slot. The protrusion is configured to at least partially depress as the hook is inserted into the slot and engage with the indentation when the hook is positioned to engage with the slot. The hook and the slot, when engaged, resist separation of the second component from the first component. The protrusion and the indentation, when engaged, resist disengagement of the hook from the slot.
