Rope connection system, devices, and methods

A system configured to join at least two ropes, the system comprising:

• a first rope that defines a first outer diameter;
• a second rope that defines a second outer diameter;
• and
• a device configured to join the first rope to the second rope, the device including a device body that extends from a first end to a second end along a central axis, the device body including an inner surface defining a through hole that extends through both the first end and the second end, the device body defining an inner dimension measured from a first point on the inner surface to a second point on the inner surface along a straight line that is both perpendicular to and that intersects the central axis,
• wherein the device defines an unassembled configuration in which:
• 1) an entirety of the first rope is positioned outside the through hole, 2) an entirety of the second rope is positioned outside the through hole, and 3) the inner dimension is smaller than both the first outer diameter and the second outer diameter, and
• wherein the device defines an assembled configured in which:
• 1) a portion of the first rope is positioned in the through hole, 2) a portion of the second rope is positioned in the through hole, and 3) the inner dimension is greater than both the first outer diameter and the second outer diameter.
