A clip or clamp is provided comprising a spiral strip (10) and a driving or actuating member (18) engageable with slots or slits (16, 17) in one end of the strip (10), whereby rotation of the driving member (18) about an axis normal to the surface of the strip (10) in one direction causes the spiral (10) to contract and rotation in the other direction causes the spiral (10) to expand. The driving or actuating member (18) is rotatably mounted in a housing (12) secured to the other end of the strip (10). The driving or actuating member (18) is provided with teeth or threads (23) which engage the slots or slits (16, 17) in the strip (10). The driving oractuating member (18) is slidable in the housing (12) between a first position in which the threads or teeth (23) engage the slots or slits (16, 17) in the strip (10), and a second position in which the threads or teeth (23) are disengaged from the slots or slits (16, 17), thereby providing a quick release of the clip, so that the first-named end of the strip (10) can be manually fed through the housing (12). |
