Snap-type fastening device

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.
