The cash registers at a place I worked had this for the PS2 keyboard connection, too. IIRC, you needed to slide back a sleeve before giving the cable a tug. All this was behind the tight counter, buried under a layer of dust and whatever else fell behind the register. A skilled coworker could do it with one hand, but I never mastered that skill.
