Abstract
Abstract The disclosed invention relates to a plastic holding element especially intended for the fastening of at least one pipe or tubular member to a support structure. The element includes a bearing portion 3 for the pipe and an attaching portion 2 for connecting to the support. The bearing portion 3 of the holding element has at least one zone of material softer than the plastic of the body of the holding element. The softer material is joined to at least one surface of the bearing portion 3 by a two shot injection molding process. The bearing portion 3 may be designed either in the form of individual nodes 4 or in the form of inlays (7, 13 and 7', 13').
