Abstract: The present invention relates to a curtain retainer. The curtain retainer is comprised of a retainer element having a pair of parallel elongate members having a gap therebetween and having inside and outside faces. A support is provided to support the retaining element from a wall, ceiling, head rail of a window blind or curtain, or the like. A plug is provided for insertion into and retained within the gap in the retaining element. The plug clampingly engages fabric of a curtain between itself and corresponding inside faces of the members. The plug is retained in a partly recessed position within the gap and is capable, in this position, of retaining the fabric sufficiently loosely to allow for positioning of the fabric in pleats or the like.
