A sectional ski composed of a forward and a rear section which interlock forward of the boot supporting region of the ski. The sections, preferably made of fiberglass, have male and female coupling members composed of aluminum or other lightweight but strong metal, molded as an integral part of the respective sections. The front coupling member, serving as the rear portion of the front section, consists of a recessed area which also houses a pair of eccentrically mounted cams. These cams engage and disengage the interlocking surfaces of cam slots in both sides of the male lock insert which serves as the front portion of the rear section of the ski. As the two sections are slidably engaged, the cams draw the coupling members together laterally and lock them into an integral unit. The two sections are further held in place by the close tolerances of the vertical and horizontal interfaces of the metal coupling members which are beveled at their points of juncture and by an insert of compressible urethane which serves as a packing gland between the two coupling members.
