1. Structure for the removable connection of two generally tubular members, comprising:

  • first and second tubular members of relative diameters such that said first member may be longitudinally received within said second member, said first and second members comprising relatively flexible and rigid material, respectively;

    at least one slot formed longitudinally within said second member;

    at least one opening defined through the circumferential wall of said second member, said opening being adjacent an end segment of said slot, circumferentially displaced from the longitudinal axis of said slot, and defining a projection camming surface contiguous with said slot;

    at least one projection formed substantially radially outward on the outside of said first member, and adapted so as to be guided in said slot when said first member is longitudinally introduced into said second member, with said first member being radially compressed during such introduction so as to provide radially outward biasing for said projection to snap same outward into said opening so as to frictionally engage said opening when said first member is circumferentially twisted relative said second member once said projection has longitudinally penetrated said second member adequate to reach said slot end segment;

    wherein reversed twisting of said first member for moving said projection towards said slot forces said projection against said projection camming surface which radially depresses said projection and said first member so as to frictionally disengage said projection from said opening such that said projection will reenter said slot to be withdrawn therealong for decoupling said first and second tubular members.
