Abstract
An end of a convoluted metal hose is connected to an adaptor having an end surface which is rounded to complement a contour of an endmost convolution. A straight section of the convoluted hose extends unbonded some distance through a bore in the adaptor, where it is welded in place. This way any flexing is by a section of the wrapping over the rounded end, the wrapping section being remote from any heat damage which may result from the welding. The internal transition between the bores of the hose and adaptor is straight and smooth, free of any crevice.
