A track assembly for flexible pool covers. The track assembly includes track members, and securing pieces for being secured to the pool deck and for splicing the track members together in an end-to-end series. The securing pieces are designed to reside beneath, and to be concealed by, the tracking members. The securing pieces may be attached to a pool deck with fasteners, after which the track members may be snapped downwardly onto the securing pieces to thereby secure the track members to said securing pieces. The track members conceal the securing pieces, and the fasteners that secure the securing pieces to the pool deck, thereby providing an aesthetic appearance of continuous tracking uninterrupted by fasteners, fastener holes, or other through holes. This arrangement prevents the fasteners from coming loose and posing a risk to barefooted bathers, because the upward movement of the fasteners is inhibited by the track members that reside above the fasteners.
