Abstract: A gripping device comprises: at least two end walls located at opposing ends of the device; at least one elongate channel for receiving an elongate element, the longitudinal axis of the or each channel extending between the two end walls; a gripping element; and biasing means for bringing the gripping element into engagement with an elongate element located in the said channel. The gripping element is mounted for translational movement in a slot. A force component exerted on an elongate element located in the said channel causes the gripping element to move in the slot at towards the elongate element. Each end wall includes at least one hole therethrough, a first hole for receipt of an elongate element into the said channel and a second hole for exit of said elongate element from said channel.

Abstract: A gripping device comprises a body having a longitudinal axis and including at least one elongate opening for receiving an elongate element, a gripping element, and means for bringing the gripping element into engagement with an elongate element located in the said opening, wherein the gripping element is mounted for translational movement in a slot having a longitudinal axis, and the longitudinal axis of the slot is set at an acute angle to the longitudinal axis of the opening, and wherein a force component exerted on an elongate element located in the said opening causes the gripping element to move in the slot and towards the elongate element, and wherein said opening is defined by walls and wherein one of the walls includes two intersecting surfaces lying at an angle to one another, the angle between the two surfaces being concave.

Abstract: A connector assembly is used in connecting one duct section to another, at least one of the duct sections being an insulated duct. The assembly comprises a plurality of first elements, and a plurality of second elements, each first element including attachment means for attachment of an end face of a duct section thereto, and, in use, at least one second element engages with two first elements.
