Abstract: A flower mounting pin device, including a combination body and safety pin, is disclosed. The cross-shaped body includes an upright member and a transverse crossbar. The upright member includes projecting nubs and a through hole spaced along it. The crossbar includes a transverse pin channel with a central keyslot, and a hinged cover which closes over the pin channel to secure the safety pin within the pin channel. The crossbar and the hinged cover further include mating male and female elements to secure the cover in its closed positon over the pin channel. The safety pin includes a stationary arm which fits in the pin channel of the crossbar. The stationary arm has a central offset portion which extends into the central keyslot, securing the safety pin against rotation and translation within the pin channel. Various sizes of safety pins can be used, all with the same benefits.
