The insert 30 may be received in one of the recesses 14 formed between the opposing surfaces of the wing extensions of the upper and lower walls 18, 20. The insert 30 is provided with a linear slide surface 32, which linear slide surface 32 projects laterally from a vertical wall 34. Extending over the entire length of the insert 30. The sliding surface 32 can be regarded as a bearing surface. The sliding surface 32 is convex in the same shape as the recess 14 of the guide element 10.

The insert can be fixed in position by the slightly convex shape of the opposite surfaces of the wing extensions of the upper wall 18 and the lower wall 20 of the guide element 10. Further, at the front and/or rear vertical wall 22 of the body 12, the ends of the upper and lower walls 18, 20, i.e., the wing extensions, may be formed such that the spacing therebetween is slightly reduced in order to secure the insert in place.

Referring to fig. 3, there is shown a system for suspending a curtain device, the system comprising a tubular rail 40 made of metal, for example aluminium alloy or plastics, having on its underside a longitudinally extending slot 42 defined by two opposed flanges 44 projecting laterally. Wall 46, wherein a portion 48 of flange 44 provides a bearing surface 50 for guide element 10. Portion 48 may be formed to slope toward slot 42, for example, portion 44 may form a circular arc segment. The slot 42 is at least as wide as the width of the gap of the guide element 10, so that the portion 48 of the flange 44 is received in the recess 14 of the guide element 10. The sliding surface 32 provides a bearing surface for the bearing. The guide element 10 is adapted to engage with a support surface 50 of the guide rail 40.
