ABSTRACT The present invention relates to cellular plastic insulating tubes or cellular plastic insulating plates of a flexible plastic foam with a groove- and tongue-like closing system arranged along the longitudinal axis, in which the groove and tongue can be undercut. The tongue consists of a more rigid or stiffer material than the material forming the groove, or, if the tongue consists of the same material as the insulating cellular material, this is reinforced or stiffened.
