A clamp comprising: a tubular member, wherein the tubular member has: an elongated tubular shape with a lengthwise slot disposed therein between a first end and a second end longitudinally opposite the first end, the slot having a width extending between a first longitudinal edge of the tubular member defining a first side of the slot and a second longitudinal edge of the tubular member defining a second side of the slot, a protrusion that extends out of an inner surface of a lengthwise cavity within the tubular member, the protrusion being offset with respect to the slot such that the protrusion is disposed within the tubular member closer to the first or second side of the slot to create an asymmetrical cross section in the tubular member; and a locking member, wherein the locking member has a thickness smaller than the width of the slot and a width greater than the width in the slot allowing the locking member to be inserted into and out of the slot in a first orientation but not in at least one other orientation.
