Abstract

A fastener comprising first and second separable members, for engaging an elongate element. Each member includes first and second complementary shaped partial-cylindrical portions formed on a facing side thereof. The first and second partial-cylindrical portions of the first member have outside dimensions that are complementarily dimensioned with respect to the inside dimensions of the first and second partial-cylindrical portions of the second member, so that the first and second partial-cylindrical portions of the first member selectively engage and nest within the first and second partial-cylindrical portions of the second member when the facing side of the first and second members are positioned towards each other. The elongate element is engaged between the first and second members of the fastener by an engagement area formed when one of the first and second partial-cylindrical portions are nested.

Claims

1. A fastener for engaging an elongate element, comprising:

first and second separable members, each member including first and second complementary shaped partial-cylindrical portions formed on a facing side thereof,

wherein the first and second partial-cylindrical portions of the first member have outside dimensions that are complementarily dimensioned with respect to inside dimensions of the first and second partial-cylindrical portions of the second member, so that the first and second partial-cylindrical portions of the first member selectively engage and nest within the first and second partial-cylindrical portions of the second member when the facing side of the first and second members are positioned towards each other, thereby forming a rotatable pivot point for said first and second members when the first partial-cylindrical portions of the first and second members are nested,

and wherein the elongate element is engaged between the first and second members of the fastener by an engagement area formed when one of the first and second partial-cylindrical portions are nested.

2. The fastener of claim 1, wherein the first partial-cylindrical portions have a tubular shape so as to form a hollow as said engagement area in the center of the rotatable pivot point.

3. The fastener of claim 2, wherein the first and second members are formed of a flexible plastic material so as to facilitate a snap engagement the first partial-cylindrical portions of the first and second members when they nest.

4. The fastener of claim 1, wherein the second partial-cylindrical portions have a tubular shape so as to form a hollow engagement area therein when they are nested.

5. The fastener of claim 4, wherein the hollow engagement area formed by the nesting of the second partial-cylindrical portions is shaped so as to also engage the elongate element.

6. The fastener of claim 4, wherein the first and second members are formed of a flexible plastic material so as to facilitate a snap engagement the second partial-cylindrical portions of the first and second members when they nest.

7. A fastener for engaging an elongate element, comprising:

first and second separable members, each member including first and second complementary shaped partial-cylindrical wall portions formed on a facing side thereof,

wherein the first and second partial-cylindrical wall portions of the first member have outside dimensions that are complementarily dimensioned with respect to inside dimensions of the first and second partial-cylindrical wall portions of the second member, so that the first and second partial-cylindrical portions of the first member selectively engage with a snap fit so as to nest within the first and second partial-cylindrical portions of the second member when the facing side of the first and second members are positioned towards each other, thereby forming a rotatable pivot point for said first and second members, and

wherein at least one hollow centered at said rotatable pivot point is created by the nesting of one of the first and second partial-cylindrical portions, said hollow being dimensioned for engaging the elongate element.

8. The fastener of claim 7, said hollow is created in the center of the rotatable pivot point.

9. The fastener of claim 7, wherein the first and second members are formed of a flexible plastic material so as to facilitate a snap engagement of the first partial-cylindrical wall portions of the first and second members when they nest.

10. The fastener of claim 7, wherein first and second hollows are formed by the nesting of the first and second partial-cylindrical wall portions, respectively, both hollows being shaped so as to engage the elongate element.
