The hose (10) further comprises an axial strengthening means (20) adapted to reduce deformation of the tubular body (12) when the tubular body (12) is subjected to axial tension, the axial strengthening means (20) being adapted to exert a radially inward force on at least part of the tubular body (12) when axial strengthening means (20) is subjected to axial tension. ## Claims ### Claim 1 A hose comprising: a tubular body of flexible material arranged between an inner and an outer helically wound wire, the tubular body serving to transport fluid through the hose and to prevent fluid leakage through the body, wherein the tubular body comprises at least one reinforcing layer and at least one sealing layer; and an end fitting fitted to an end of the hose, wherein the end fitting comprises: an inner member adapted to be disposed at least partially within the hose; and sealing member comprising a sealing ring adapted to seal at least part of the tubular body between the sealing ring and the inner member and a compression member for compressing the sealing ring into sealing engagement with said part of the tubular body, wherein the compression member is tightenable against the sealing ring in order to selectively increase or decrease the compression force of the compression member against the sealing ring, and wherein the compression member is made from a material which contracts less than the sealing ring when subjected to cooling. ### Claim 2 (depends on 1) A hose according to claim 1, wherein the compression member and the sealing ring are removably securable to the hose. ### Claim 3 (depends on 1) A hose according to claim 1, wherein the compression member is adapted to compress the sealing ring equally in all directions. ### Claim 4 (depends on 1) A hose according to claim 1, wherein the compression member includes a tightening means for adjusting the compressive force applied by the compression member to the sealing ring. ### Claim 5 (depends on 4) A hose according to claim 4, wherein the compression member is of adjustable diameter, and wherein the tightening means can apply a force to reduce the diameter of the compression member, thereby compressing the sealing ring within the compression member. ### Claim 6 (depends on 1) A hose according to claim 1, wherein the compression member comprises a split ring or a jubilee clip. ### Claim 7 (depends on 1) A hose according to claim 1, wherein the compression member is stainless steel and the sealing ring is polytetrafluoroethylene. ### Claim 8 (depends on 1) A hose according to claim 1, wherein the outer surface of the inner member is provided with at least one formation thereon which is adapted to engage said part of the tubular member, underneath the sealing ring. ### Claim 9 (depends on 1) A hose according to claim 1, wherein the sealing ring is an interference fit with the inner member.
