Hi Arne, 

go to the plugin.xml file, and then all you have to do is :

       <popupPredefinedItem id="deleteFromDiagramAction" remove="true"/>

under the extension point : 

  <extension 
point="org.eclipse.gmf.runtime.common.ui.services.action.contributionItemProviders">


This is what i have for an element of my model : ActivyEditPart.
 

	<extension 
point="org.eclipse.gmf.runtime.common.ui.services.action.contributionItemProviders">
      <?gmfgen generated="false"?>
       <contributionItemProvider 
class="org.eclipse.gmf.runtime.diagram.ui.providers.DiagramContributionItemProvider"
            checkPluginLoaded="false">
         <Priority name="Low"/>

 <popupContribution 
class="org.eclipse.gmf.runtime.diagram.ui.providers.DiagramContextMenuProvider">
            <popupStructuredContributionCriteria 
objectClass="com.isoco.iwf.designer.bpmn.diagram.edit.parts.ActivityEditPart"/
>
            <popupPredefinedItem id="addNoteLinkAction" remove="true"/>
            <popupPredefinedItem id="fileMenu" remove="true"/>
           <popupPredefinedItem id="cut" path="/editMenu/copyGroup" 
remove="true"/>
			<popupPredefinedItem id="copy" path="/editMenu/
copyGroup" remove="true"/>
			<popupPredefinedItem id="paste" path="/editMenu/
copyGroup" remove="true"/>    
            <popupPredefinedItem id="deleteFromDiagramAction" 
remove="true"/>
            <popupPredefinedItem id="deleteFromModelAction" 
remove="false"/>
            <popupPredefinedItem id="formatMenu" remove="true"/>
            <popupPredefinedItem id="filtersMenu" remove="true"/>
            <popupPredefinedItem id="showPropertiesViewAction" 
remove="true"/>
            <popupPredefinedItem id="properties" remove="true"/>
         </popupContribution>
hope it helps.
