Then, a portion of the connector 340 may bet fitted into the half-slot 321 of the slot 320. In some embodiments, the connector 340 may comprise a spring operable to bias the portion of the connector 340 that is fitted into the half-slot toward the portion of the connector 340 located below the slot 320.

Referring now to FIGS. 6A-6B, cross-sectional views of the connector 340 and slot 320 are shown. The connector 340 may comprise a main body 602 operable to fit through the opening 319 of the slot 320. The connector 340 may comprise a piston 606, wherein the piston 606 may connect to the main body 602. In some embodiments, the piston 606 may connect to the main body 602 with a screw 604. The connector 340 may also comprise a base 608, wherein the piston 606 and the main body 602 may be operable to move with respect to the base 608. In some embodiments, the connector 340 may comprise a screw 610 located about the piston 606 , wherein the spring 610 may be located between a bottom portion of the piston 606 and a portion of the base 608.

In some embodiments, the connector 340 may comprise a cover 614 operable to attach to the base 608 to protect the spring 610 and the piston 606 from the outside environment and movement. In some embodiments, the main body 602 may comprise a clip shaped part (or clip) 603 operable to fit about a breathing air hose, for example. In some embodiments, the clip 603 may extend through the top of the slot 602, allowing a hose 330 (shown in FIG. 3) to be held by the clip 603. In some embodiments, the main body 602 may comprise other attachments for holding other elements of an SCBA system in place, depending on the placement of the connector 340.

In some embodiments, the base 608 may attach to an axis 612, wherein the axis 612 may attach the connector 340 to a strap 310. The strap 310 may fit around the axis 612 and may be operable to rotate with respect to the base 608. In some embodiments, the strap 210 may be removed and replaced, while the connector 340 may be reused.

In the embodiment shown in FIG. 6A, the main body 602 of the connector 340 has been pulled upward and passed through the opening 319 of the slot 320. The spring 610 may be compressed between the base 608 and the bottom portion of the piston 606 by the upward movement of the main body 602 (and therefore of the piston 606) .

In the embodiment shown in FIG. 6B, the main body 602 and therefore the piston 606 may have been rotated approximately 90 degrees, and lowered into the half-slot 321 of the slot 320. In the embodiment shown, the piston 606, the screw 604, the main body 602, and possibly the spring 610 may rotate freely with respect to the base 608. With the main body 602 resting in the half-slot 321, the spring 610 may be uncompressed, and therefore may bias the main body 602 downward toward the base 608. The spring 610 may secure the main body 602 within the half-slot 321, wherein the main body 602 would be required to be lifted upward against the spring’s bias and rotated approximately 90 degrees for the main body 602 to pass through the opening 319 and out of the slot 320. This movement of lifting and rotating the main body 602 may be accomplished easily by a user, but may be unlikely to happen spontaneously without action by the user. The spring bias may ensure that the connector 340 may not get loose accidently due to factors such as vibration or movement by the user.

The half-slot 321 and the main body 602 may be shaped similarly, such that the main body 602 fits securely within the half-slot 321, but may be easily lifted out of the half-slot 321 by a user. Similarly, the opening 319 may be shaped similarly to the half-slot 321 and the main body 602, such that the main body 602 fits easily through the opening 319, but may be unlikely to slip through the opening 319 without action by the user.
