ABSTRACT:
An end fitting for a sheathed, convoluted conduit comprises a generally tubular body member having a threaded portion adjacent one end for screwing into the conduit bore and a frusto-conical portion spaced from the threaded portion which tapers inwardly away from that one end and around which the sheath of the conduit is to be received, and clamping means for clamping the sheath against the frusto-conical surface comprising an annulus surrounding the frusto-conical portion which is deformable to conform to the frusto-conical portion.
The body further includes a plain cylindrical portion intermediate the threaded and frusto-conical portions for receiving the end few convolutions of the conduit and defining a radial shoulder against which the conduit end is to abut, and means adjacent the other end for mounting the fitting on a support.
