Coupling members for closure devices and systems

A coupling device comprising:

• a female component including:
• a main body portion having a top surface and a bottom surface;
• and
• a coupling aperture that is accessible from the top surface of the main body;
• and
• a male component including:
• a main body portion having a top surface and a bottom surface;
• and
• a coupling member having a tab that extends downward from the bottom surface of the coupling member and a flange that extends distally from the tab;
• wherein the coupling aperture and the coupling member are configured such that coupling of the male component and the female component is achieved by insertion of the coupling member's flange within the coupling aperture while the male component is oriented at an angle relative to the female component and is further achieved by rotating the male component downward after the flange is inserted into the coupling aperture such that after rotation of the male component, the male component and the female component are roughly aligned;
• wherein the coupled male and female components have a cross sectional area and wherein the coupled components exhibit a failure strength of between about 560 and 840 Newtons per square centimeter of cross sectional area.

A coupling device comprising:

• a female component having:
• a main body portion having an upper surface, a lower surface, and opposing side surfaces;
• and
• a single coupling aperture positioned roughly equidistant from each side surface of the opposing side surfaces, the single coupling aperture being accessible from the upper surface of the main body portion;
• and
• a male component having:
• a main body portion that includes a top surface and a bottom surface;
• and
• a single coupling member that extends from a distal end of the main body and that is mateable with the single coupling aperture of the female component to couple the male and female components together;
• wherein the male and female components are non-releasable from a coupled engagement until after tension is released from a tension member, and wherein the coupled male and female components have a cross sectional area and exhibit a failure strength of between about 560 and 840 Newtons per square centimeter of cross sectional area.
