If your clamp are not "Piping part" but "SharedSupport" type :

in the above rules the Clamp is supposed to be a Piping Part Occurence

IF you are using "Support" Object type for Clamp then you must define in the rule the Clamp object as a "SharedSupportPartOccurrence"

--> the above rule must be adjust :

Warning : Today 23x-24xGA this code doesn't work because the function to get Object form PipeOcc "GetRelatedObjects()" doesn't return the "SharedSupportPart" object type --> need to investigate on how to retreive "SharedSupportPartOccurence" from Pipe Occurence

Current code for Piping Part Occ

//create a new list that contains only PipingPart with subtype =Clamp
for i while i <= NbPartList
{
    set PartOcc = PartList.GetItem(i)
    PartRef=PartOcc.Reference
    set PartSubType = PartRef.GetAttributeString("V_SubPartType")
    if PartSubType=="Clamp"
    {
        ClampList->AddItem(PartOcc,j)
        j=j+1
    }
}

To be replaced by following : 
First , declare the variable for "Support"
Let SupportOcc (SharedSupportPartOccurrence)  // Support occurence attached to the pipe
create the list of support per pipe
//create a new list that contains only Support object type
for i while i <= NbPartList
{
    set SupportOcc = PartList.GetItem(i)
    ClampList->AddItem(SupportOcc,j)
    j=j+1
}
