To interconnect the portions (5, 6) and the portions (7, 8) of the conduits (3, 4) in a coupling element of an air or electric micromotor to a dental hand piece, the connection conduits (9, 10) are drilled diagonally in the base (1) of this element. The passages (15, 16) are provided between the outlets (11, 12) of the connection conduits (9, 10) and the inlets (13, 14) of the portions (7, 8) of the conduits (3, 4) and secured by means of the screw (17) provided with the seal (18). To clean the assembly of conduits (3, 4), it only takes to remove the screw (17) and the seal (18). |
