• wherein when said male portion is released from said female portion, said strap gripping bar slides into the release position and allows adjustment of said strap, and
• wherein said strap gripping bar has two ends and two protrusions at each end, and wherein there are two apertures in each of said sidewalls, a first one of said protrusions on each end of the strap gripping bar extending through a first one of said apertures on each of the sidewalls to connect said strap gripping bar to said male portion, and a second one of said protrusions on each end of the strap gripping bar extending through a second one of said apertures on each of the sidewalls so that the second protrusions can be raised and lowered to pivot the strap gripping bar to adjust the strap.
