(54) Spacer for radiators with tubular elements


(57) A radiator (R) for space heating has been described with tubular elements (1) that are connected by special spacers (2; 2.i, 2.c, 2.t; 12) between which said tubular elements (1) are placed.
According to the invention said spacers (2; 2.i, 2.c, 2.t; 12) are
- firmly fastened to a side of at least one adjacent tubular element (1) by means of threaded fasteners (3, 2.2; 9.1, 1.4),
- able to keep two consecutive tubular elements (1) at the set distance between each other,
- have passages (2.3; 9.2) that guarantee hydraulic connection between the distribution pipes (1.1) of said two consecutive tubular elements (1),
whereas water-tightness is ensured by means of special seals (4) placed between said spacers (2; 2.i, 2.c, 2.t; 12) and said tubular elements (1).
