Underlying the art

Fasteners for pipes to documents such as ceilings, walls and floors of buildings, as well as metal parts such as sheet metal parts, for example, automobiles are usually made of pipe-clamp-like elements which receive the pipe and must be specifically attached to the respective documents at specified intervals.

Tube assemblies for heat exchange purposes are used for heating or cooling, and also to control the temperature of the home, and can also be for temperature control of technical systems and widely used wherever it on a temperature of surfaces, even larger areas as sports facilities, road bridges and the like matters.

For example, in a floor heating system which is laid under screed, the aforementioned document includes an insulation panel of foam or mineral wool, which optionally bears a support plate and is at the opposite flat sides, if necessary, covered with sealing films. This insulation serves as a thermal and impact insulation. On this insulating panel, a structural steel mat, for example, moved, the part is supported by support elements which are formed for receiving the pipe for the heating medium (DE-A-2807446). After laying of the pipes and their connection means the entire assembly is sealed with screed.

There are also other arrangements of this type have become known in which the tubing is routed through tacking (DE-B-3125318) on the insulation board.

Through the US-A-3,288,136 a pipe assembly of the aforementioned type for locking the tubes of catheters or cannulas against longitudinal displacement is known, wherein the first adhering connection part surrounds the locking device and extending therethrough flexible plastic pipe. The second adhering connection part is adhesively bonded to a preselected location on the patient's skin. Then, the flexible plastic tube is placed in the desired position and it moved along the first bonding part together with the locking device until the alignment for the second bonding part. Thereafter, the first adhering connection part is connected by pressing down with the second bonding part. At the same time the locking device and the flexible plastic tube are deformed such that the flexible plastic tube clamped in the desired position and is secured against longitudinal displacement.

It is also known to use such adhesive joints as adhesive fastener elements in garments.

The foregoing and many other prior art tube assemblies have the disadvantage that they require special intermediate elements between the base and the tube, which must be specially prepared and optionally attached using special tools to the support or laid, around the pipe into the shape desired in each case apply the pad and connect to each predetermined locations with the pad.
