A rail for a fabric of a window covering, the rail including a rail profile extending elongately in a first direction and laterally in a second direction between a fabric edge and a wedge edge, the second direction being perpendicular to the first direction, and a wedge. The rail profile includes a first wall and a second wall extending in the first direction and extending in the second direction between the fabric edge and the wedge edge, the first wall being separated from the second wall in a third direction perpendicular to the first and second directions, the first and second walls having inner surfaces, the inner surfaces facing each other, and a middle wall extending in the first direction and extending between the first and second walls. The middle wall and the first and second walls together define a wedge channel for receiving the wedge and a fabric channel for receiving a fabric of a window covering. The middle wall is at least partially elastic and the first wall, the second wall and the middle wall may be configured such that, with the middle wall in a relaxed state, the inner surface of the first wall and the inner surface of the second wall at the fabric edge define there between a fabric entrance through which the fabric is able to pass into the fabric channel and the inner surface of the first wall and the inner surface of the second wall at the wedge edge define there between a wedge entrance to the wedge channel. The wedge extends in an elongate direction and has a cross section along the length of the elongate direction including a triangular portion tapering from an apex to a wide portion. The middle wall includes an elongate deflection protruding in the second direction towards the fabric edge and defining the wedge channel with an extension in the second direction towards the fabric edge to accommodate the apex of the wedge when positioned within the wedge channel. The extension of the middle wall from the inner surface of the first wall to the inner surface of the second wall includes, in succession, extension in the second direction towards the fabric edge, then extension in the third direction, then extension in the second direction towards the wedge edge, thereby to provide the elongate deflection. The midpoint of the middle wall between the inner surface of the first wall and the inner surface of the second wall is closer to the fabric edge than to the wedge edge.
