Some embodiments disclosed herein provide an apparatus for joining two skis to form a splitboard. The apparatus can comprise a first attachment portion configured to attach to a first ski and a second attachment portion configured to attach to a second ski. The first attachment portion and the second attachment portion can be configured to engage to prevent splitboard skis from moving up and down relative to each other, from moving apart in a direction perpendicular to a seam of the splitboard, from sliding relative to each other in a direction parallel to the seam, and from rotating about the seam of the splitboard.
