An introducer for dispensing a flexible member such as a catheter has a receptacle extension having a plurality of sections. Some of the sections are configured to have their own given dimensions. The dimensions may be in the form of a given tapered conical configuration for each of the sections so that those sections each are adapted to only fittingly mate with the receptacle of a counterpart connector that has a configuration complementary to the given tapered conical configuration. The introducer is thus usable with connectors of different configurations.
