A ring-type body is provided comprising a plurality of closed continuous convolutions of wire and one end portion of the wire, of an angular extent somewhat less than 360 degrees, includes a slightly greater radius of curvature whereby it is spaced outwardly of the adjacent convolutions. The end portion terminates in a smoothly curved back turned portion defining a U-shaped seat structure for embracingly receiving the free end portion of the plunger of a syringe structure immediately inwardly of the diametrically enlarged terminal end flange thereof, the flange of the syringe plunger being clamped between the U-shaped seat structure and the opposing outer surface portions of the adjacent convolutions. The entire ring-type body including the integral wire portion defining the aforementioned U-shaped seat is constructed from a single length of wire material.
