Claims2
A pin stem clutch for detachable securement to a post comprising a base body member having a central pin receiving aperture and having upwardly turned integral ends, said ends bent in respective arcs toward each other, the terminal portion of each arc secured to the body member at the end of the arc on its side of the aperture so that a smoothly curved loop is formed at each side of the aperture, whereby for each loop the entire arc on opposite sides of diametrically opposite portions enters into the resilient action of gripping of a pin by reason of the transfer of the pin pressure across the arc and the flexing of opposite sides of the arc.
