Connection tip for a dental device for universal application according to claim 23, further comprising a hollow cylindrical body (100) having one of:

i) an internal bore (100a) and on its outer periphery locking means (13) which comprises a quarter-turn bayonet system whose pins (13a), extending from the cylindrical body (100), cooperate with housings (13b) of complementary shapes formed in the inner wall of the elongated body (2),
ii) an internal bore (100a) and, on its outer periphery, locking means (13) which comprises an elastically deformable system (13c) comprising, on the outer periphery of the cylindrical body (100), at least two resilient blades (13d) which become lodged during the fastening of the connecting tip (10a to 10j) in a window (13e) of complementary profile formed in the elongated body (2),
iii) an internal bore (100a) and on its outer periphery locking means (13) which comprises a magnet system (13f) comprising, at the end of the cylindrical body (100) and on its outer periphery, a magnetically charged metal ring (13g) which becomes magnetized on a magnetically charged metal ring (13h) fixed inside the elongated body (2),
wherein the internal bore (100a) of the hollow cylindrical body (100) comprises, on the side of the locking means (13), a first opening (100b) allowing the passage and positioning of the thrust axis (6) in the connection tip (10a to 10j), and
the hollow cylindrical body (100) comprises, opposite the first opening (100b), a threaded head (100c) having in its center a hole of small diameter (100d) opening inside the internal bore (100a), said threaded head (100c) allowing the fastening of a needle holder (14), a part of the needle (14a) cooperating with the hole (100d) to come out inside the bore (100a) in order to tightly cooperate with a capsule (15) filled with anesthetic liquid and provided with a push rod (15a) coming into contact with the thrust axis (6) when said tip (10a) is locked inside the elongated body (2).
