<p>An improved hose clamp of the kind comprising a steel strip (2) bent to annular shape with the end portions (5, 6) of the strip overlapping. The radially outer strip end portion (6) is formed on its external face with a lengthwise threaded passageway (7) having transverse grooves engaging the threads (8) of a headed worm (4). The worm is rotatably journalled in a sleeve (1) but axially non-slidable therein, said sleeve (1) enclosing the screw worm and comprising a space allowing the outer strip end portion (6) to be moved between the inner strip end portion (5) and the worm (4) by rotating the latter. The worm sleeve (1) is formed with lugs (10) gripping the outer strip end portion (6) at the radially inner face thereof and the inner strip end portion is formed with matching notches (11), the lugs (10) being insertable into said notches in abutment against the inner face of the outer strip end portion (6). The worm sleeve (1) is arranged, after interconnection of the lugs (10) and the notches (11) of the inner strip end portion (5) to prevent lengthwise movements of the inner strip end portion (5) relative to the worm sleeve (1).</p> |
