ABSTRACT:
In order to avoid the necessity of having a range of sizes of tools for the mounting and removal of a plurality of resiliently deformable plugs of different transverse dimensions on the ends of associated tubes, there is provided a plurality of such plugs which can all be mounted on, or removed from, the ends of the associated tubes using the same tool. In the plugs, each of which comprises a circular disc portion, an annular skirt portion projecting from the periphery of the disc portion to one side thereof, and a pin member which projects in the direction of the longitudinal axis of the plug from the center of the disc portion to said one side thereof, with the skirt portion presenting an outwardly directed annular closure member having an outer diameter which is reducible by resilient deflection of the disc portion to either side thereof, the transverse cross-sectional dimensions of the pin members of the plugs are the same. Furthermore, the pin member of each plug is circular in transverse cross-section thereby to facilitate, during the mounting or removal of the plug, applying a force which results in the resilient deflection of the disc portion of the plug being substantially symmetrical about the center of the disc portion so that the reduction in the outer diameter of the annular closure member during this operation is substantially uniform.
