<p>One mouth at least is turned towards the panel-type element, in a wall or elsewhere, in attachment of a pipe duct to such an element, esp. temporarily or occasionally. A section of a fixture device (3) connectable to the panel element (2) is sited in this mouth (12). The device is activated from the side of the panel facing away from the duct (1), to engage the duct internal walling. The section (5) protruding into the mouth can be an elastic socket which is shortened for radial widening. This provides secure inmovable pipe fixture, with mouth sealing. It is quick and easy, and can be used repeatedly.</p> |
