Abstract
Hose clamps are disclosed comprising a band, band section, or attachment to a band, which yields in a direction circumferentially of the band and which possesses a spring-like quality and/or action such that the clamp is essentially self-adjusting to compensate for thermal expansion and contraction of the assembly (clamp, hose and fitting), as well as for the aging or cold set which the hose undergoes, whereby a fluid-tight seal is maintained throughout the intended life of the assembly, without requiring the clamp to be re-tightened. The bands of the clamps are open-ended and of generally circular configuration and are provided with a tangentially located or oriented worm drive screw for closing the clamp and providing a greater and closer range of adjustment in closing the clamp. The clamps, in some cases, have incorporated therein a positive stop, whereby closure of the clamp can be limited to a specified or predetermined size or diameter.
