<p>A batten assembly (5) comprising, a batten member having an elongate main body portion (14) with two opposed ends and a cavity (19) extending between the ends along the length of the main body portion, an elongate retaining member (17) shaped so that it may be fitted into the cavity and held therein, an end opening at each of the two ends providing access to the cavity, a lengthwise opening defined between opposed forward edges (20) of the main body portion, the lengthwise opening giving access to the cavity along its length, an external step (21) proximate each forward edge (20), a resilient clip (15) having two arms (26) shaped so that the clip may be pressed on to the main body portion with a forward portion of each arm snap fitting over one of the steps to hold the resilient clip on the main body portion, and a cord receiving aperture (32) at a rear portion of the resilient clip, wherein the construction is such that a thin web of material (3) may be fed through the lengthwise opening into the cavity to sandwich the thin web of material between the elongate retaining member and the main body portion and the external profile of the main body portion comprises a gradual ramp (23) leading to each step so as to gently expand the forward portions of two arms away from each other as the resilient clip is pushed on to the body portion and to allow the forward portions to sharply retract towards each other as they are pushed over the steps.</p> |
