Abstract: 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).

Abstract: The invention relates to an annular connection clamp with a first clamping flange (22) which protrudes radially inwards and with an axial counter bearing (24) which is spaced from the clamping flange and which is made of a first and a second half-ring segment (20), each half-ring segment having a first and a second segment end. The first segment end of the first half-ring segment (20) has latching means (281) of a first type, and the second segment end of the second half-ring segment has corresponding latching means (282) of a second type, said latching means being pushed into each other in a tangential direction, thereby being latchable together. The second segment end of the half-ring segment (20) has latching means (282) of a second type, and the first segment end of the second half-ring segment (20) has latching means (281) of a first type, said latching means being pushed into each other in a tangential direction, thereby being latchable together.
