Abstract
Abstract An integrally formed clamping band is initially offset from an end of an elastomeric hose, with a close fit on the relaxed normal outer diameter of the hose. A nipple, adapted for an interference fit with the bore of the hose, is inserted into the hose end to effect radial expansion of the hose bore. Upon axially opposed forces being applied to the nipple and hose, the outer diameter of the hose is sufficiently contracted for the cylindrical band to be freely movable along the contracted hose into a final clamping position over and around the nipple. Upon relaxation of the tension, the clamping band maintains clamping compression of the embraced section of the hose end of the nipple. In the case of braid reinforced hose, the braided reinforcement radially contracts the elastomeric hose wall material into tighter engagement with the nipple, upon the hose being subjected to tension. As an alternative to inducing tension in the hose, and after the nipple has been inserted into the hose end, the nipple and clamping band may be relatively oppositely moved to effect relative translation of the clamping band into final clamping position.
