ABSTRACT:
A coupling for connecting an elastic hose to a rigid tube connection is provided, which tube connection has a peripheral, rigid rim, at least one rigid supporting member with a radially inward facing annular supporting surface being arranged so as to offer support to the hose end at the tube connection, in which the coupling includes an inner ring having two end portions, the inner ring being arranged so as, in a mounting state, to have its end portions mutually overlapping and lending the inner ring a smaller diameter than the hose and, in a mounted state inside the hose, directly opposite the inward facing supporting surface, to be expanded by the pressing-together of its end portions, end to end, to maintain a chosen larger diameter in order, within the hose, to clamp the hose end between the inner ring and the inward facing supporting surface, and in which the cross section of the inner ring is shaped with an arcuate portion and the supporting surface in the supporting member is correspondingly arched.
