Abstract
A security hydraulic coupling system includes at least two hydraulic connector fittings (4, 5) which may be connected to adjacent fluid ports (1, 2) of a hydraulic unit (12) and which are linked to each other by means of a base plate (3) which is also shaped to cooperate with at least one projection (10) on the hydraulic unit (12) to thereby physically prescribe the positions of the various elements during the steps of fitting connection and disconnection. An interlock system comprises a security pin (6) which is housed in the base plate (3) and is mounted between the fittings (4, 5) and cooperates with grooves (7, 8) provided in the fittings (4, 5) to prescribe the possible sequence of steps in connecting/disconnecting the fittings (4, 5) from the ports of the hydraulic unit (12).
