<p>The coupler has aquaplane immovably connectable or connected base boards (1,2) with an axial guide (3). A pair of holders (10,20) holds a toe-side end and heel-side end of a shoe and axial engages with guide, and is extended and movably connected to axially adjustable coupling rail (30). An actuatable locking element moves between lock position and release position in which holder (10) is axially fixed/engaged and released from coupling rail in relative to the base board. The coupling rail is extended to axially move in a channel (4) under the base board.</p> |
