The invention relates to a connection device comprising —a line portion (10) having, at its end, a radially outwardly projecting abutment flange (14) for butting against a corresponding abutment flange of a further line portion which is to be coupled to the line portion (10), and—a ring-segment chain (42, 22, 38) comprising a plurality of ring segments (22, 38) connected to one another in a pivotable manner in a common ring plane, wherein the ring-segment ends which formed the chain ends can be latched to one another to give a ring-form connection clamp (42). The invention is distinguished in that the line portion is designed in the form of a tubular connection stub (10) with first thread means (16) spaced apart axially from the abutment surface (141) of its abutment flange (14), and in that each ring segment (22, 38) has a radially inwardly projecting clamping flange (24) and second thread means (26), which are spaced apart axially from said clamping flange and correspond with the first thread means (16).

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

An apparatus for facilitating delivery of conditioned air across a barrier in a cage for holding an animal patient to a blanket arrangement providing the conditioned air to the patient. The apparatus comprising a first duct part, a second duct part and a mounting mechanism arranged to mount the first duct part on one side of the barrier and the second duct part on the other side of the barrier opposite thereto, to provide a duct for ducting conditioned air across the barrier. The barrier comprising bars or mesh, and the apparatus further comprising a seal arrangement to provide at least a partial seal across the bars or mesh. The mounting mechanism comprises a fastening mechanism for fastening the first and second duct parts to each other across the barrier, wherein the fastening mechanism is a keyhole-style fastening arrangement utilising a plurality of headed projections on a flange of the first duct part engagable with respective keyhole-style apertures on a flange of the second duct part.

A fire damper for an air distribution system includes a body defining a flow path and a closure means adapted to close the flow path when a temperature within the flow path exceeds a predetermined maximum temperature. A first flange is fixed to the body and a mounting means comprising a second flange is slidably engageable with and removable from the body. The mounting means comprises securing means for securing the mounting means to the body such that a building element through which the fire damper extends, in use, can be clamped between the first and second flanges. A flexible insulating sleeve configured for use with a fire damper, and a method of installing a fire damper, are also disclosed.
