Claim 13

A positionable clip engageable about a component disposed on an elongated rod for provisionally capturing the component at a position on the rod, said positionable clip comprising: a clamping member including a pair of arms arranged to simultaneously contact the elongated rod on substantially opposite sides thereof, and means for biasing said pair of arms together to provide a gripping force on the rod when the rod is disposed between said pair of arms; and a bar connected to said clamping member and having a length extending substantially parallel to the rod when the rod is disposed between said pair of arms, said bar including a surface directed toward the rod disposed apart in relation to the rod when the rod is disposed between said arms, said surface configured to contact the component to capture the component in a position on the rod; wherein said means for biasing includes a resilient hinge connected between said pair of arms.

Claim 14

The positionable clip according to claim 11, wherein said bar is resiliently biased toward the rod when the rod is engaged between said pair of arms, whereby said bar applies a clamping force against the component.

Claim 15

The positionable clip according to claim 11, wherein said clamping member further includes a pair of tabs extending from a corresponding one of said pair of arms, said tabs arranged relative to said resilient hinge to deflect said hinge when said tabs are depressed toward each other, whereby said pair of arms are disengaged from said rod.

Claim 16

The positionable clip according to claim 13, wherein said bar constitutes one of said pair of tabs.

Claim 17

A positionable clip engageable about a component disposed on an elongated rod for provisionally capturing the component at a position on the rod, said positionable clip comprising: a bar having a length between first and second ends, said length sized to span a length of the component along the elongated rod when the component is disposed thereon; a pair of upper arms, one each connected to said bar at a respective one of said first and second ends, each of said upper arms defining a clamping surface directed toward the rod when said positionable clip is capturing a component on the rod; a lower arm connected to said bar between said first and second ends, said lower arm defining a lower clamping surface directed toward the component when the component is disposed on the elongated rod; and biasing means for biasing said pair of upper arms towards said lower arm to provide a gripping force on the elongated rod and the component engaged between said upper arms and said lower arm; wherein said lower arm includes a first end connected to said bar and a free second end, wherein said first end defines a pressure surface facing the component disposed on the rod when said positional clip is capturing a component on the rod, whereby a force applied to said pressure surface causes said clamping surface of each of said pair of upper arms to slide around the rod to deflect said pair of upper arms against said means for biasing.

Claim 18

A positionable clip engageable about a component disposed on an elongated rod for provisionally capturing the component at a position on the rod, said positionable clip comprising: a bar having a length between first and second ends, said length sized to span a length of the component along the elongated rod when the component is disposed thereon; a pair of upper arms, one each connected to said bar at a respective one of said first and second ends, each of said upper arms defining a clamping surface directed toward the rod when said positionable clip is capturing a component on the rod; a lower arm connected to said bar between said first and second ends, said lower arm defining a lower clamping surface directed toward the component when the component is disposed on the elongated rod; and biasing means for biasing said pair of upper arms towards said lower arm to provide a gripping force on the elongated rod and the component engaged between said upper arms and said lower arm; wherein said lower arm includes a first end connected to said bar and a free second end, wherein said first end defines a pressure surface facing the component disposed on the rod when said positional clip is capturing a component on the rod, whereby a force applied to said pressure surface causes said clamping surface of each of said pair of upper arms to slide around the rod to deflect said pair of upper arms against said means for biasing.

Claim 19

The positionable clip according to claim 15, further including a lever arm connected to said bar and operable against said biasing means to disengage said upper arms and said lower arm from the elongated rod.
