ABSTRACT:
In a coupling formed of two components, one of which has a body portion with a bore having a taper to give a decreasing diameter towards an entry end of the bore, a collet having resilient arms being located in the bore and the second component having a tube adapted for insertion into said collet through the entry end to be gripped thereby, the tapered bore causing the grip to be tightened if the second component is pulled in the outward direction from the bore in the first component, in order to prevent separation of the components after assembly, the collet has a portion protruding out of the first component through said entry end of the bore and the second component has a portion extending around the protruding end of the collet and the two components having surfaces which abut to prevent the collet being pressed inwardly into the bore in the first component by moving the two components towards one another.
