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'"'"').

Claims

1. A plastic holding element mounting at least one tube member on a support, comprising a relatively rigid moulded plastic body having a tube bearing portion and a mounting portion for attaching the body to a support, the holding element bearing portion having at least one inlay defining a tube engaging surface formed of softer material than the plastics of the holding element, characterized in that the inlay (7,7'"'"';

13,13'"'"') is formed of softer and less rigid material than the plastics of the holding element and that the inlay is permanently connected and bonded to a surface of the bearing portion (3,3'"'"') through at least one key type connecting element (8;

9) by being directly moulded to said connecting element and said surface by a two component moulding process.

2. A holding element according to claim 1 characterized in that the inlay (7) has at least one recess opening (10).

3. A holding element according to claim 1 wherein said bearing portion comprises a base part and a cover part connected therewith through a hinge, characterized in that the base part (11,11'"'"') and the cover part (12,12'"'"') are provided with an inlay (7,7'"'"';

13,13'"'"'), respectively.

4. A holding element according to claim 3, characterized in that the inlays (7;

13) of the cover part (12) and the base part (11) have an opening (10,14) passing therethrough, respectively.

5. A holding element according to claim 4, characterized in that the inlays (7,13'"'"') of the cover part (12'"'"') have several chamber-like openings (10'"'"',10",10"'"'"') separated from each other by stay members (19,20).

6. A holding element according to claim 3, characterized in that the inlays (7,13'"'"') in the base part (11'"'"') and in the cover part (12'"'"') are designed for different diameters of tubes (21,22).

7. A holding element according to claim 6, characterized in that the base part (11'"'"') and the cover part (12'"'"') are provided at least on certain portions of the exterior with an inlay (23;

24).
