A power returnable tape rule has an improved connection between the outer end of the power spring and the inner end of the coilable rule blade provided by interengaging element thereon. The rule blade has an elongated aperture adjacent its inner end with the margins of the blade defining the aperture including opposed inwardly extending finger portions. The tongue is configured with spaced transversely extending shoulders facing in opposite directions, and it extends along the upper surface of the rule, downwardly into the aperture under the fingers and upwardly from the aperture and forwardly thereof along the upper surface of the rule blade. The shoulders on the tongue of the spring abut the margins of the aperture adjacent the finger portions in either direction of relative longitudinal movement to limit such movement and retain the two elements in assembly.
