<p>A hose coupling, particularly for use with fire hoses, the halves of which are provided with latch rings, the latch rings being rotatable relative to hose unions associated with each half, the latches of which can be engaged by a bayonet fitting with a chamfered annular groove in the latch ring in the other half of the coupling, whereby rotation of the latch ring causes the hose unions to close up to each other in an axial direction in order that sealingrings arranged in their respective faces can be pressed axially against each other, without rotation relative to each other, and in which the hose unions include means for internally fitting and securing the hose which comprises an expandible clamping ring which, after being expanded, secures the hose against inner walls of the hose union.</p> |
