ABSTRACT:
A tool for tightening an annular clamping band around a hose includes a substantially V-shaped forming punch adapted to be pivoted to an active position by a reciprocating pneumatic actuator. As the punch pivots to its active position, it rams part of the free end portion of the band into a substantially V-shaped throat formed in an anvil. The actuator then shifts the punch and the anvil in a direction applying tension to the band as the band is drawn between and is reshaped by the punch and anvil.
