Claim:
A blade for weld free connection within a torque converter, which torque converter comprises a pump, and a turbine, each of said pump and turbine comprising a rotatable assembly having a hollow shell, having an external convex surface in the shape of a toroidal section as defined by cutting through a torus along an external circumference and having an internal concave surface corresponding to its external convex surface, said blade having an edge shaped so that at least a portion of the edge can be coextensive with the internal surface of the hollow shell with which it is to be connected and so that a major part of said coextensive portion can be inserted into a depression in the internal surface of the shell with which it is to be connected, said blade further comprising at least one tab for passage through a slit in the shell that can be bent on a portion that passes from the internal surface, through a slit in the shell, to secure the blade to the external convex surface of the shell.
