| 摘要 |
The invention is a device (10) for providing a clamping force about a connection end of elastomeric hose or tubing (14). The device includes an at-least-twice-oriented polymer having a shrinkage response to each of at least two diameter reducing release temperatures, which is sized and formed into a band (10). The clamp is self-adjusting over a substantial working life. The band may be installed onto connection ends of hose or tubing and fixtures such as couplings, inserts or stems (16) without the external applicaiton of heat, preferably preselecting the first diameter reducing release temperature to be at roughly room temperature. The clamp displays improved constrictive forces over prior art polymer clamps.
