A flexible hose is secured to a fitting using elongated strips and band clamps in a conventional manner so as to prevent relative longitudinal movement between the flexible hose and the elongated strips. One end portion of each of the elongated strips is bent back so as to be contiguous to the next succeeding portion of the elongated strip so as to form a shoulder and a recess is formed in the fitting. The bent back portions are seated in the recess and retained therein by a band clamp acting on the next succeeding portion so that relative longitudinal movement between the elongated strip and the fitting is prevented by an abutting relationship between the shoulder of the bent back portion and a shoulder of the recess.

Apparatus for restraining relative longitudinal movement between a fitting and a flexible hose comprising: a relatively rigid fitting; means forming at least one shoulder on said fitting and extending in a circumferential direction; said fitting having a longitudinally extending first outer surface

Apparatus for restraining relative longitudinal movement between a fitting and a flexible hose comprising: a relatively rigid fitting; means forming at least one shoulder on said fitting and extending in a circumferential direction; said fitting having a longitudinally extending first outer surface extending from adjacent to said one shoulder to one end of said fitting; a flexible hose around said first outer surface; said fitting having a longitudinally extending second outer surface extending from adjacent to said one shoulder toward the other end of said fitting; at least two separate and elongated strips of material, each of said strips positioned to extend in a direction parallel to the longitudinal axis of said fitting; one end of each of said elongated strips comprising a longitudinal portion that is bent back so as to be adjacent to the next succeeding longitudinal portion to form a shoulder on each of said elongated strips; said shoulders on said elongated strips being located in direct abutting relationship with separate and circumferentially offset portions of said one shoulder so that longitudinal movement in substantially the direction of said one end of said fitting between the shoulder on each of said elongated strips and said one shoulder towards each other is limited by contact between the shoulder on each of said elongated strips and the corresponding said separate and circumferentially offset portion of said one shoulder, and so that substantially all of a longitudinal force applied to said elongated strips in substantially the direction of said one end of said fitting will be directly communicated to said separate and circumferentially offset portions of said one shoulder; said elongated strips being positioned free from contact with each other; the other end of each of said elongated strips being located over a portion of said flexible hose; a first band clamp, positioned over said bent back portion and said next succeeding portion of each of said elongated strips, for holding said bent back portion of each of said elongated strips adjacent to a portion of said second outer surface, and for retaining the shoulder on each of said elongated strips in direct abutting relationship with said one shoulder; and at least a second band clamp around portions of said flexible hose and portions of each of said elongated strips for effecting a seal between said flexible hose and said first outer surface of said fitting and for preventing relative longitudinal movement between each of said elongated strips and said flexible hose.
