Combined mobile electronic device holder and fastener mechanism

A mobile electronic device holder, the holder comprising:

• a container for holding a mobile electronic device, the container having a substantially continuous closed tubular walled body, the body comprising:
• an open upper end opposing a closed lower end;
• a rear wall having a front surface and a rear surface;
• a front wall;
• a pair of lateral side walls, wherein the front wall and the rear wall are integrally joined substantially perpendicular by the pair of lateral side walls, the rear wall, the front wall, and the pair of lateral side walls each integrally extends vertically from the closed lower end;
• an interior cavity;
• an attachment mechanism;
• a support plate suitably mounted to the attachment mechanism, wherein the rear surface of the rear wall of the body is suitably mounted to the support plate;
• and
• a retainer element, wherein the open upper end of the body provides ingress into the interior cavity formed within the body, the interior cavity defines a volume suitably dimensioned for accepting a mobile electronic device and removably holding the mobile electronic device securely therein in a snug-fit manner, the rear wall includes an upper edge forming a pair of shoulders between which a neck portion integrally extends vertically therefrom, the shoulders creating a space bilateral to the neck portion allowing an upper portion of the mobile electronic device to be free of contact with the rear wall, thereby facilitating quick, easy, and efficient grip and removal of the mobile electronic device from the interior cavity, the front wall defines a height measuring less than a height defining the rear wall, and wherein the front wall includes a relief formed therein as an elongated, wide slot which extends downward intermediate from an upper edge of the front wall into the interior cavity of the body.
