Abstract
Clip apparatus for use in securing a member such as a hose to a pipe or the like. The apparatus includes a housing secured to one end of a spirally configured flexible strip. A rotatable driving member carried by the housing is formed with threads engageable with complementary threads formed on the strip. Rotation of the driving member causes expansion and contraction of the strip relative to the pipe or the like. Slidable movement of the driving member disengages its threads from those of the strip.
Claims10
Clip apparatus, comprising:
- a housing;
- a flexible spiral shaped strip having its first end secured to said housng and formed along its outer surface with a plurality of teeth, the end of said strip opposite that secured to said housing extending through said housing;
- and
- a rotatable driving member slidably carried by said housing for longitudinal movement relative to said strip between first and second positions, said driving member having a substantially flat face formed with a second plurality of teeth so shaped that they engage the teeth of said strip when said driving member is disposed in its first position and rotation of said driving member about an axis normal to said flat face causes expansion and contraction of the spiral shape of said strip, with the teeth of said driving member being disengaged from the teeth of said strip when said driving member is moved longitudinally towards the second end of said strip to the second position of said driving member so as to permit the spiral shape of the strip to be adjusted independently of rotation of the driving member.
