A vertical rail, a lower holder (16) as well as an upper holder (20), adjustable on a support arm (22), are provided on an attachment surface on which the upper holder can pivot to attach onto the heating unit. The upper holder has a claw-like holder piece (34) at its free end which is located in such a way and provided with such a starting incline (52) that the claw-like holder piece can be moved away by against an opposing force. The claw-like holder is displaceably located in a U-shaped section 36 of the upper holder so that its movement is translational and that the opposing force is produced by a spring projecting from the holder piece or a flexible lug (30). |
