<P>PROBLEM TO BE SOLVED: To prevent the occurrence of such a situation that an erroneous operation is caused by external contact and a coupling which should be in a locked state is unintentionally separated, and to surely perform a connection operation and a release operation. <P>SOLUTION: This hose coupling is characterized in that, in a final connection state, at least a part of a remaining pawl (second pawl 42) shifted from a depth side from the tubular axis direction among respective groups of the accommodated pawls is housed in an axial position which is within each concave section of a socket member and overlaps with each convex portion by the elastic restored displacement of the socket member 2. A hose coupling is configured so as not only to be seized by the elastic pressure of an axial elastic material as usual but also to make the remaining pawl accommodate therein by leading the remaining pawl (second pawl 42) to the forward side of the rotating direction of the convex portion of a socket and to partially overlap axial position of the convex portion and the axial position of the accommodated remaining pawl mutually by the elastic restoration of the convex portion of the socket. <P>COPYRIGHT: (C)2013,JPO&INPIT |
