In various embodiments of the present invention, the removable connection comprises a tab extending from the strap that engages with a complementary slot disposed on the holder, complementary magnets, and other such types of removable connectors. The housing of the holder further includes a secondary compartment or receptacle. The secondary receptacle can be disposed about the exterior surface of the holder and can include a lid for preventing the entry of water into the interior volume thereof.
