The invention claimed is: 1. Hydraulic circuit element (20), for heat exchange between a first and a second fluid, which defines a path for the first fluid, comprising at least one tube (22) having two ends and at least one tip (24) at one of said ends of the tube (22), said tip having at least one
The invention claimed is: 1. Hydraulic circuit element (20), for heat exchange between a first and a second fluid, which defines a path for the first fluid, comprising at least one tube (22) having two ends and at least one tip (24) at one of said ends of the tube (22), said tip having at least one communicating passage (28b) that defines the path of the first fluid, said tip (24) comprising a strip of sheet metal defining two branches (31) and an upstand (42) connecting the two branches (31) along respective edges, the upstand (42) forming an enclosed receiving cap that receives one of said ends of the tube as the end extends past said at least one communicating passage (28b) and seals it to prevent fluid flow from said end. 2. Circuit element according to claim 1, wherein said tube or tubes (22) are generally flat and/or said tip or tips (24) are fastened to the ends of said tube or tubes (22). 3. Circuit element according to claim 1 wherein it comprises a single tube (22) having a terminal tip (24) at each of its ends. 4. Circuit element according to either of claims 1 and 2, characterized in that it consists of several tubes (22), an intermediate tip (124) being present between two successive tubes (22). 5. Circuit element according to claim 4, characterized in that it has a rectilinear shape. 6. Circuit element according to claim 4, characterized in that it has a broken shape. 7. Circuit element according to claim 1, characterized in that said tip (24) or at least one of said tips consists of a strip of sheet metal folded to form two branches (31) of equal length. 8. A Hydraulic circuit element (20), for heat exchange between a first and a second fluid, which defines a path for the first fluid, comprising at least one tube (22) having two ends and at least one tip (24) at one of said ends of the tube (22), said tip having at least one communicating passage (28b) that defines the path of the first fluid wherein said tip (24) or at least one of said tips consists of a strip of sheet metal folded to form two branches (31) of unequal length. 9. A Hydraulic circuit element (20), for heat exchange between a first and a second fluid, which defines a path for the first fluid, comprising at least one tube (22) having two ends and at least one tip (24) at one of said ends of the tube (22), said tip having at least one communicating passage (28b) that defines the path of the first fluid wherein said tip (24) or at least one of said tips has two bosses (26) aligned along the longitudinal axis of said tube or tubes (22). 10. Circuit element according to claim 1 wherein said tip (24) or at least one of said tips has two bosses (26) aligned along a direction perpendicular to the longitudinal axis of said tube or tubes (22). 11. Circuit element according to claim 1, characterized in that said tip (24) or at least one of said tips has two pairs of bosses (26), the two bosses of one and the same pair being aligned along a direction perpendicular to the longitudinal axis of said tube or tubes (22). 12. Circuit element according to claim 9 wherein said tip (24) includes a strip of metal defining two branches (31), characterized in that a communicating channel (54) is formed in at least one of said two branches (31) of the tip (24) in order to establish a flow of the first fluid between the bosses (26). 13. Heat exchanger for a motor vehicle comprising a stack of circuit elements (20) according to claim 1 that communicate via said tips (24) in order to allow said first fluid to pass between said circuit elements. 14. Heat exchanger according to claim 13, wherein some of the tips (24) have bosses (26) via which the circuit elements (20) come into contact when they are stacked, in such a way that the bosses (26) of one circuit element (20) rests on the bosses (26) of the adjacent circuit elements (20). 15. Heat exchanger according to claim 13, characterized in that it includes an inlet nozzle (58) and/or an outlet nozzle (60) having a flattened end matching the available space between the ends of the two adjacent circuit elements (20). 16. Heat exchanger according to one of claims 13 to 15, characterized in that it has two fastening tabs (64, 66) that are fastened to the tips (24) of the circuit elements (20). 17. Circuit element according to claim 2, wherein it comprises a single tube (22) having a terminal tip (24) at each of its ends. 18. Circuit element according to claim 2, wherein said two branches (31) comprise an unequal length relative to each other. 19. Circuit element according to claim 2, wherein said tip (24) or at least one of said tips has two bosses (26) aligned along the longitudinal axis of said tube or tubes (22). 20. Circuit element according to claim 2, wherein said tip (24) or at least one of said tips has two bosses (26) aligned along a direction perpendicular to the longitudinal axis of said tube or tuber (22). 21. Heat exchanger for a motor vehicle comprising a stack of circuit elements (20) according to claim 2 that communicate via said tips (24) in order to allow said first fluid to pass between said circuit elements. 22. Heat exchanger according to claim 21, wherein some of the tips (24) have bosses (26) via which the circuit elements (20) come into contact when they are stacked, in such a way that the bosses (26) of one circuit element (20) rests on the bosses (26) of the adjacent circuit elements (20). 23. A hydraulic circuit element (20) as set forth in claim 1 wherein said at least one tip (24) includes a perforation (44, 45) disposed between each of said two branches (31) and said upstart (42).
