A TUBE CONNECTING ELEMENT OF PLASTIC FOR SANITARY AND HEATING PURPOSES, COMPRISING TWO CONNECTING SLEEVE ELEMENTS FORMING A COMMON FLOWTHROUGH BORE AND BEING IN ALIGNMENT WITH RESPECT TO ONE ANOTHER, INTO THE BORES OF WHICH PLASTIC TUBES MAY BE WELDED, AND FURTHER COMPRISING A SLEEVE BODY BETWEEN THE TWO CONNECTING SLEEVE ELEMENTS AND FORMING THEREWITH A UNITED ENTIRETY, WHICH SLEEVE BODY IS PROVIDED WITH A BORE EXTENDING PERPENDICULARLY TO THE BORES OF THE CONNECTING SLEEVE ELEMENTS AND SERVING FOR THE RECEPTION OF A THIRD PLASTIC TUBE. IN ORDER TO AVOID DEFORMATION OR FATIGUE OF MATERIAL IN CONNECTION WITH SUCH A DEFORMATION AND THUS TO INCREASE THE RESISTANCE AND LIFETIME OF SUCH TUBE ELEMENTS UNDER COMPARABLY HIGH INSIDE PRESSURES AND INSIDE TEMPERATURES THE CONNECTING TUBE ELEMENT IS PROVIDED WITH A BORE CONNECTING THE TWO BORES OF THE CONNECTING SLEEVE ELEMENTS, WHICH BORE IS WITH RESPECT TO THE CENTER LINE OF THE TWO BORES PROVIDED WITH A CENTER LINE OFFSET IN THE DIRECTION WITH THE OUTER WALL OF THE T-CONFIGURATED TUBE CONNECTING ELEMENT LOCATED OPPOSITELY TO THE PERPENDICULARLY EXTENDING BORE, WHICH CONNECTING BORE IS PROVIDED WITH A DIAMETER B SMALLER THAN THE DIAMETERS A1, A2 OF THE BORES OF THE CONNECTING SLEEVE ELEMENT, AND WHICH IS SEPARATED FROM THE PERPENDICULARLY EXTENDING BORE BY ITS BOTTOM WALL HAVING A THICKNESS C CORRESPONDING GENERALLLY TO THE WALL THICKNESS D1 OF THE CONNECTING SLEEVE ELEMENTS AND BEING JOINED WITH THE PERPENDICULAR EXTENDING BORE BY A BORE, THE CROSS SECTION THEREOF BEING IN GENERAL SMALLER THAN THE WALL THICKNESS D1 OF THE CONNECTING SLEEVE ELEMENT THAN THE CROSS SECTION OF THE PERPENDICULARLY EXTENDING BORE.(FIG.2)
