In combination, an improved track device and spline member used as a fastener system for securing flexible cover or sheet materials, wherein the combination comprises: an elongated track having a base member, a pair of oppositely disposed side-wall members, and inwardly projecting rail members; a channel defined by said base member, said side-wall members, and said rail members; said base member being formed with a pair of inclined, inner-wall surfaces centrally positioned in said channel and having a V-shaped configuration, the outer marginal edges thereof being fluted to define oppositely positioned, recessed, longitudinal grooves; said side-wall members being formed with inner, tapered wall surfaces, each inclined inwardly and upwardly of said channel; said rail members being formed with inner, tapered wall surfaces that are inclined inwardly and downwardly of said channel; a spline member having a central body member of semi-rigid material; and a pair of wing members formed from a substantially rigid material and integrally formed with said central body member, whereby said wing members are readily repositioned to be inserted in said channel so as to lockingly engage the flexible sheet material interposed between said track and said spline.
