1. A connector comprising:
a joint member including a tubular outer wall;
a bracket secured to the tubular outer wall, the bracket including a first bracket through hole that extends along a first axis, the bracket further including a second bracket through hole that extends along a second axis that is perpendicular to the first axis;
a sleeve having a first sleeve through hole that extends along a third axis, the sleeve further including a second sleeve through hole that extends along a fourth axis that is perpendicular to the third axis;
a pin insertable through both the second bracket through hole and the second sleeve through hole to rotatably couple the bracket and the sleeve; and

wherein a width of the intermediate portion measured perpendicular to the first direction is less than a width of the first terminal end portion and is also less than a width of the second terminal end portion, and
wherein the yield plate is securable to the bracket via insertion of a first fastener through both the first bracket through hole and the first plate through hole, and the yield plate is securable to the sleeve via insertion of a second fastener through both the first sleeve through hole and the second plate through hole.
