ABSTRACT:
A multi-part STORZ type coupling comprises a pair of similar and complementary coupling units. Each unit comprises assembled inner and outer annular parts which are threaded together and fixedly attached. Each inner annular part has a pair of similar spaced forwardly projecting lugs at a front-end portion and each lug has a radially outwardly projecting ear at its free end portion. Each outer annular part has a diametrically enlarged front-end portion which accommodates an annular groove opening radially inwardly. Circumaxially spaced forwardly open notches permit the lugs of a complementary coupling unit to be entered rearwardly through the notches into the groove. When the lugs have been so entered and rotated to an assembled position the parts of the coupling may be fixedly attached to each other.
