ABSTRACT:
A ski includes at least two sections interconnectible end-to-end, one section having a recess sunk in an end portion thereof and the other ski section having a tongue projecting from an end portion thereof, the recess and tongue shaped to closely interfit when the ski sections are assembled, end-to-end, thereby to provide a full length ski, there being structure to positively and releasably interconnect said end portions in assembled condition. A method of forming the ski assures tight interfit of the recess and tongue; and the tongue cannot be inadvertently pulled from the recess.
