ABSTRACT OF THE DISCLOSURE A mechanism and method for operating a device for crimping a metal outer sleeve of a hose connector around the end of a flexible hose. The device has a constrictor collet assembly for radially inwardly deforming the sleeve in response to axial movement of the collet assembly in a frusto conical die ring. Axial movement is imparted by a ram and a pair of pusher members mounted between the ram face and the collet assembly. The pusher members are swung between open and closed positions by the operating mechanism which has a pair of lever arms connected to the pusher members at one end and to a pintle at the other end. The pintle is slidably mounted for lateral movement in a slot. It is resiliently biased towards a forward end of the slot such that one element of the operating mechanism can be advanced to a first position whereat the pusher halves are closed and then further advanced to a second position into contact with a switch that activates the ram and causes the pusher members to shove the constrictor collet assembly axially deeper into the frusto conical die ring.
