ABSTRACT:
A connector for a tube comprises a hollow spigot and an outer securing member for capturing a tube therebetween. The hollow spigot includes an internal bore matched to that of the tube, a tapered end with a frusto-conical length and its small diameter at its distal end and a parallel length inwards of the tapered end, with a diameter less than the maximum tapered diameter and an annular rib inwards of the parallel length to provide an end stop for the tube when fitted onto the spigot. The outer securing member includes an internal tapered bore matched to the frusto-conical length and of respectively increased diameter to accommodate the tube therebetween and at least one latch formation spaced from the member's large tapered end for engaging behind the annular rib.
