A hydraulic connector having a first assembly releasably connected to a second assembly. The first assembly includes a substantially cylindrical body having a longitudinal bore therethrough and a receptacle portion surrounding the longitudinal bore. The first assembly has an internal circumferential chamber therein. The chamber has an upper portion and a lower portion. The second assembly includes a substantially cylindrical body having a longitudinal bore therethrough and a protruding portion having an external circumferential groove. A movable locking ring is housed in the lower portion of the chamber. The locking ring has a first surface to matingly engage the circumferential groove. A piston is slidably received in the chamber. The piston is permitted to move axially relative to the first assembly. The piston has an upper head and a lower head connected by a sleeve segment. The piston and the chamber form individual chambers for locking and unlocking. The locking chamber can be pressurized to force the piston to a locked position in which the locking ring matingly engages the circumferential groove. The unlocking chamber can be pressurized to force the piston to an unlocked position in which the locking ring is not matingly engaged with the circumferential groove.
