Hose with intermediate coupling

Abstract

A hose with in intermediate coupling which is capable of optimally holding a nipple at a regular position corresponding to a sleeve by caulking the sleeve, in which a pair of inclined surfaces 4a, 4b are arranged so as to correspond to two positions 2a, 2b at which a sleeve is caulked, the inclined surfaces 4a, 4b making small outer diameter portions and a large outer diameter portion of a nipple 4 contiguous. As a result of the construction, forces F.sub.1, F.sub.2 for caulking the sleeve are transformed into forces f.sub.1, f.sub.2 being opposed to each other, and the balance of these two forces f.sub.1, f.sub.2 causes the nipple 4 to move to a regular position corresponding to the sleeve. Even after the sleeve has been caulked, stresses remaining in a hose at the two positions are received by the pair of inclined surfaces 4a, 4b, which are like the sides of a truncated cone, so as to confront the inclined surfaces, thereby blocking further movement of the nipple.
