Abstract
Abstract An apparatus for locking together simultaneously one or more male and female coupling members is disclosed, primarily for use in undersea hydraulic applications. The apparatus comprises a sliding lock plate supported by a first junction plate, the plate being slideable perpendicular to the coupling axis between an unlocked position and a locked position. The sliding lock plate has a number of passages configured to receive each coupling member therethrough in the unlocked position. In the locked position, the passages are configured to engage the circumference of the male and female coupling members and restrict axial movement of the members.
