Abstract
The connection for releasably joining two drum components of a hydraulically-actuated double friction disc clutch includes first and second drum components having circular cylindrical surface directed substantially axially, one overlapping the other. The inner component is formed with a catch groove or two catch recesses and the outer drum component includes catch projections, offset mutually 180.degree. and adapted to become locked within the catch groove. The outer drum includes tabs at an axial end adapted to fit within recesses formed on the periphery of the inner drum between catch projections. The drums are driveably connected by applying oppositely directed axial force sufficient to snap the catch projections into the catch groove. The drums are disassembled by elastically deforming the outer drum until the catch projections clear the catch groove and then applying an axial force that separates the drums.
