Abstract: An anchorage system includes an elongate track defining an interior channel and an anchorage device securable at any of plural longitudinal positions on the track. The track has a base and first and second sides. A longitudinal channel opening opens in an outward face of the track and is defined between first and second retaining flanges at the outward face. The flanges project in towards one another and overlay the interior channel. The flanges have edge faces directed laterally towards one another across the channel opening and outward surfaces which are comprised in the outward face of the track. The anchorage device has a body, a retaining foot and a stem portion connecting the body and the retaining foot. The foot is laterally wider than the stem portion, and the anchorage device is engageable in the track with the foot in the interior channel.
