A crimping machine for radially inwardly crimping an end fitting onto a hose by means of a contractible die assembly includes a reciprocable ram. A pusher assembly is mounted on the ram for transmitting ram force to the die assembly. The pusher assembly includes first and second semicircular pusher members, and the pusher members are mounted for axial movement with the ram and for lateral movement relative to the ram. The die assembly includes two disjuncted die sections, one of which is carried on the end of each pusher member by connecting means which permits relative radial movement between the die section and the pusher member. A cam follower on each pusher member follows a cam surface on the machine for moving the pushers laterally outwardly when the die sections are pulled from the socket by the pushers during retraction of the ram. During advancing movement of the ram, the cam surfaces close the pusher halves and the die sections carried on the pusher halves to form a die cavity in which the workpiece is located. Further advancing movement of the ram after the pushers and die sections come together forces the die sections into a conical socket to radially inwardly deform the workpiece.
