ABSTRACT:
The invention relates to a hose coupling whose halves are held together by identical cam rings (Storz coupling). For the solution of the problem to construct the connections which are to be arranged in the halves of such couplings to be short and light and in one piece and consequently without sealing problems even when the outer diameter of the connection is as large or even larger than the diameter of the cylinder which is limited by the inside of the cams, the joining between the connection and the cam rings is of similar construction as in cam rings of coupled coupling halves in that the connection (3) at its end which is to be joined with a cam ring (1) has an extension (6) which extends radially outwardly, forms a stop and is preferably constructed as a collar. In the cam ring (1) a shoulder (9) of a recess (8) of angular cross-section which extends behind the cams (2) is provided as a counterstop for the extension. This design can be realized when the connection is a hose-fixing connection (3) as well as when it is a threaded connection. It is advantageous that the connection (3) is held in the cam ring (1) by means of a safety mechanism (5) so it cannot be lost.
