Claim:
A subsea hydraulic coupler adapted for insertion through an aperture of predetermined inside diameter in a mounting plate having a front face and a rear face, said coupler comprising: (i) a body having an internal longitudinal passageway including a valve operable to open the passageway on mating of the coupler with a complementary coupler, wherein said body is shaped for insertion through said aperture in either of two directions through the front face side or the rear face side, said body having a maximum outside diameter corresponding to said predetermined inside diameter, and the body has a circumferential groove; and (ii) a flange assembly for fitment on said body, said flange assembly comprising a plurality of separable segments, each segment comprising an axially extending hub portion which fits into the groove and a shoulder portion for abutment against said front face of the plate for both said two directions of insertion of said body; said groove and said flange assembly, when fitted on said body, are positioned on said body such that a separation force generated on said mating reacts against the shoulder portions of said flange assembly.
