Beschreibung
Zusammenfassung:	The arrangement is for producing a rigid connection between a first tube (3) and a second tube (2) into which the first tube is telescopically inserted, whereby the first tube may be a support column of an offshore platform whilst the second tube is part of the inter-connecting structure. The internal surface of a portion (14) of the outer tube (2) is provided with an annular groove (16) and the inner tube is radially expanded by momentary application of high energy so theat deformation of the inner tube into the groove forms a rigid connection. This may be effected by detonating an explosive charge (20) placed at the level of the groove in the centre of the tube (3).
