A joint coupling for axially connecting together a first joint (10) and a second joint (12), comprising: (a) a first complementary member (14) eonnected to, or integrally formed with, the first joint; (b) a second complementary member (16) connected to, or integrally formed with, the second joint, said first and second complementary members being sized and shaped so that, when properly aligned, said complementary members form an overlap structure which is effectively a continuation of the first joint or the second joint; (c) a sleeve (18) slidable over said overlap structure so as to secure the joint coupling; and (d) a first depressible member and a second depressible member (20) connected to, or integrally formed with, each other, said first and second depressible members being biased outwardly so as to prevent said sleeve from sliding off said second joint until the joint coupling is to be secured and to prevent said sleeve from sliding away from said overlap structure when the joint coupling is secured. |
