Lifting hose with ends sealed by a clamping strip

A lifting hose for raising and lowering a lift platform of a lifting apparatus useful for insertion in a bathtub, the lifting hose consisting of a fabric-reinforced, pressure-tight, flexible, substantially non-expandable material and being sealed pressure-tight at its ends by means of clamping elements, whereby each clamping element consists of two clamping strips having clamping surfaces of equal size respectively facing one another and disposed transversely to the longitudinal direction of the lifting hose, the two strips are made of plastic, a plurality of pegs aligned longitudinally protrude at right angles from the clamping surface of one of the strips, each peg having a cylindrical shank and a thickened head part, tapering towards the end, an annular collar being formed between said head part and said shank, a plurality of holes terminate at the clamping surface of the respective opposite strip, with each one of the plurality of holes in the hose strip assigned to each one of the plurality of pegs of the peg strip, when the end of the lifting hose is pressed flat, there are punched holes in the two mutually adjacent layers of material, arranged in a manner exactly matching the plurality of holes in the holed strip and having a diameter at least equal to the smallest diameter of one of the plurality of holes in the holed strip, each hole in the holed strip has, adjacent to the clamping surface, a first hole portion of small diameter for receiving the shank of one of the plurality of pegs, and a second portion of larger diameter for receiving the head part of one of the plurality of pegs, and an annular supporting surface formed between the two hole portions supporting the annular collar of one of the plurality of pegs and forming an inseparable counterbearing when the two strips are pressed together with the compressed end of the lifting hose inserted between them, the two mutually adjacent layers of the lifting hose having a thinner wall thickness in the region of the clamping surfaces than in the neighboring region, and whereby the clamping elements are attached to the hose at distances from the ends thereof respectively, and the two clamping elements are supported, in a positive fit, on counter-bearing collars formed between the two layers of the protruding edge of the hose not being pressed together, and the sections of hose pressed together in the region of the clamping surfaces, and whereby one clamping strip is greater in width when measured in the longitudinal direction of the hose than the other clamping strip and adjacent to the clamping surface of the wider strip, there is a chamber for receiving the protruding edge of the hose is formed, said chamber being determined by a front wall of said wider strip.
