A PLUG TO BE FIXED TO A TUBE BY A GLUE JOINT

摘要

The invention relates to a plug (11) to be fixed to a tube (10) by means of a glue joint, which, when the plug is glued, the glue is fed when the plug (11) is in position in the tube (10). The surface of the plug (11) to be glued or the inner surface of the tube is provided with a compensation groove (14) located essentially in the middle range of the joint, into which the glue is injected by means of at least one injection hole (12), preferably centrally and symmetrically. The glue is fitted to advance from said compensation groove (14) as two uniform fronts preferably symmetrically towards ends (11a, 11b) of the plug (11).
