ABSTRACT:
A manual locking assembly for a quick connect coupling includes a cylindrical male pin, a cylindrical sleeve-shaped female part, a rotatable key bolt, a locking bolt retainer, and a spring. The rotatable key bolt is axially arranged and central within the cylindrical sleeve-shaped female part, and has a quadrilateral locking block, a cylindrical guiding flange, and a cylindrical locking bolt having millings on opposite sides. The locking bolt retainer has a cylindrical body including a transversal hole having a radius that corresponds with an outer radius of the cylindrical locking bolt and a groove extending from the transversal hole that corresponds to the millings on the cylindrical locking bolt, a lower flange on a first side of the cylindrical body, and an upper flange located on a second side of the cylindrical body opposite to the first side, the upper flange having an inclined surface on an upper side of the upper flange. The inclined surface of the upper flange is accessible through a hole in the cylindrical sleeve-shaped female part to unlock the manual locking assembly.
