The pipe clip has a substantially annular, rigid pipe clip body which is composed of one or more parts and is provided with a securing element for securing the pipe clip body to a support. A substantially annular vibration isolating member is provided, this vibration isolating member bearing against the inner circumference of the pipe clip body and ultimately being positioned between the outer circumference of the pipe and the pipe clip body. The vibration isolating member is made from a porous elastomer material, preferably vulcanized porous rubber with closed cavities and separating walls between them. ## Claims ### Claim 1 Vibration isolating pipe clip for securing a pipe to a support, in particular for securing a medium-carrying pipe to a wall or ceiling of a building, comprising: a rigid pipe clip body which is composed of one or more parts and is provided with securing means for securing the pipe clip body to a support, a vibration isolating member which bears against an inner circumference of the pipe clip body and is ultimately positioned between an outer circumference of the pipe and the pipe clip body under elastic deformation, wherein the vibration isolating member is a porous vulcanized rubber with closed cavities and separating walls between them, wherein the cavities are substantially unpressurized by dehydration of salt which remains in the cavities, in such a manner that in the event of a reduction in the volume of the cavities under the influence of deformation of the vibration isolating member, no significant pressure increase occurs inside the cavities, wherein the vibration isolating member has a form factor defined by the quotient of the surface area which is subject to load and the free surface area, and in which the cavities significantly reduce the form factor, and wherein the form factor of the vibration isolating member is less than 0.2. ### Claim 2 Vibration isolating pipe clip for securing a pipe to a support, in particular for securing a medium-carrying pipe to a wall or ceiling of a building, comprising: a rigid pipe clip body which is composed of one or more parts and is provided with securing means for securing the pipe clip body to a support, a vibration isolating member which bears against an inner circumference of the pipe clip body and is ultimately positioned between an outer circumference of the pipe and the pipe clip body under elastic deformation, wherein the vibration isolating member is a porous vulcanized rubber with closed substantially unpressurized cavities and separating walls between them having a chemical from which water has been cleaved, wherein the unpressurized cavities when reduced in volume by deformation of the vibration isolating member, produce no significant pressure increase inside the cavities. ### Claim 3 (depends on 2) The vibration isolating pipe clip for securing a pipe to a support according to claim 2, wherein the chemical from which water has been cleaved is a salt. ### Claim 4 (depends on 3) The vibration isolating pipe clip for securing a pipe to a support according to claim 3, wherein the vibration isolating member has a form factor defined by the quotient of the surface area which is subject to load and the free surface area, and in which the cavities significantly reduce the form factor. ### Claim 5 (depends on 4) The vibration isolating pipe clip for securing a pipe to a support according to claim 4, wherein the form factor of the vibration isolating member is less than 0.2. ### Claim 6 The vibration isolating pipe clip for securing a pipe to a support, in particular for securing a medium-carrying pipe to a wall or ceiling of a building, comprising: a rigid pipe clip body which is composed of one or more parts and is provided with securing means for securing the pipe clip body to a support, a vibration isolating member which bears against an inner circumference of the pipe clip body and is ultimately positioned between an outer circumference of the pipe and the pipe clip body under elastic deformation, wherein the vibration isolating member is a porous vulcanized rubber with closed cavities and separating walls between them, and wherein the cavities are substantially unpressurized by dehydration of salt which remains in the cavities, in such a manner that in the event of a reduction in the volume of the cavities under the influence of deformation of the vibration isolating member, no significant pressure increase occurs inside the cavities. ### Claim 7 (depends on 1) The vibration isolating pipe clip of claim 1 wherein the closed cavities of the vibration isolating member have an average diameter between 0.03 and 0.7 mm, the number of cavities per mm3 is between 75 and 350, and wherein the separating walls of the closed cavities have a thickness greater than or equal to the diameter of the cavities. ### Claim 8 (depends on 1) The vibration isolating pipe clip of claim 1 wherein the closed cavities of the vibration isolating member have an average diameter between 0.05 and 0.5 mm, the number of cavities per mm3 is between 100 and 275, and wherein the separating walls of the closed cavities have a thickness greater than or equal to the diameter of the cavities. ### Claim 9 (depends on 1) The vibration isolating pipe clip of claim 1 wherein the form factor of the vibration isolating member is less than 0.1. ### Claim 10 (depends on 1) The vibration isolating pipe clip according to claim 1 wherein the vulcanized rubber with closed cavities and separating walls comprises an EPDM polymer.
