         3 . The connector according to  claim 1 ,
 wherein, the connector element has a plurality of receiving recesses.   
     
     
         4 . The connector according to  claim 1 ,
 wherein, the connector element is formed as a rosette surrounding the connector tube or is attached at the end to a bracket which is attached at the other end to the outer circumference of the connector tube.   
     
     
         5 . The connector according to  claim 1 ,
 wherein, the extension arm has at least one further receiving recess aligned transversely to the at least one receiving recess of the connector element.   
     
     
         6 . The connector according to  claim 1 ,
 wherein, on the outer circumferential side of the connector tube at least two cantilevers of identical design and each radially aligned are fastened at a defined angular distance from one another.   
     
     
         7 . The connector according to  claim 1 ,
 wherein, the tube section with enlarged outer and/or inner diameter has a plurality of shell-side locking recesses.   
     
     
         8 . The connector according to  claim 1 ,
 wherein, the tube section with enlarged outer and/or inner diameter has at the end a plurality of, for example four, axially extending elongated guide elements, which are arranged at equal angular distance from each other.   
     
     
         9 . The connector according to  claim 8 ,
 wherein, the elongate guide elements are formed at least in regions from the tube section itself and/or are reinforced by additional material in the radial direction.   
     
     
         10 . The connector according to  claim 1 ,
 wherein, a pin is formed inside the tube section with enlarged outer and/or inner diameter, which pin is arranged concentrically with respect to the tube section.   
     
     
         11 . The connector according to  claim 10 ,
 wherein, the pin has a plurality of, for example four, shell-side locking recesses, which are arranged on a circumferential line and/or at equal angular distance from each other.   
     
     
         12 . The connector according to  claim 10 ,
 wherein, the pin protrudes beyond the tube section and/or protrudes into an area of the tube section which has window-like recesses, for example for forming the elongate guide elements, so that the locking recesses are accessible from the outside.   
     
     
         13 . A modular scaffolding with at least one connector according to  claim 1  and at least one vertical post, which is inserted at the end into the tube section with enlarged outer and/or inner diameter of the connector tube for detachable connection to the connector. 
     
     
         14 . The modular scaffold according to  claim 13 ,
 wherein, the connector tube of the connector is detachably connected at the other end to a spindle or to a further vertical post.   
     
     
         15 . A method of manufacturing a modular scaffold using a connector according to  claim 1  as a scaffold node which, in the case of a system change within the modular scaffold, is used to maintain predetermined grid dimensions and to maintain predetermined clear dimensions which are required for the use of standardized scaffold components including standardized horizontal beams and/or standardized diagonal braces. 
     
     
         16 . A use of a connector as a scaffold node within a modular scaffold for maintaining predetermined grid dimensions and for preserving predetermined clear dimensions, wherein two vertical posts or one vertical post and a spindle are connected with the aid of the connector. 
     
     
         17 . The connector according to  claim 1 , wherein the connector tube has the tube section at both ends. 
     
     
         18 . The connector according to  claim 3 , wherein:
 the plurality of receiving recesses comprises one of: four, six, or eight receiving recesses; and   the plurality of receiving recesses are arranged at equal angular distance from one another.   
     
     
         19 . The connector according to  claim 5 , wherein the at least one further receiving recess is in the form of an eyelet or eye. 
     
     
         20 . The connector according to  claim 7 , wherein:
 the plurality of shell-side locking recesses comprises four recesses; and   the plurality of shell-side locking recesses are arranged on a circumferential line and/or at equal angular distance from one another.
