Abstract: A coupling device including a first member that is formed with a hooked-shaped element having a circular opening and an elongated slot that communicates with said opening, and a second member having a connecting portion that includes a circular bar and at least one leg interconnected thereto, said bar and leg being movable through said slot in oriented relation for location in said opening, wherein the bar is rotatably positioned in the opening in the hook-shaped member for coupling the members together for relative movement therebetween. A resilient friction element is mounted on the first member and partially extends into and obstructs the entrance portion of said slot as formed therein so as to prevent the members from being inadvertently disconnected.
