Abstract:
1. A device for connecting objects ( 30 , 32 ) by means of at least one connecting element ( 31 ) which can be plasticised by heat, containing a riveting tool which can be moved forwards and backwards in the direction of the connecting element ( 31 ) and has a cap ( 1 ) for forming a rivet head ( 36 ) on the connecting element ( 31 ) and a heating element ( 3 ) for heating the cap ( 1 ), wherein the heating element ( 3 ) is disposed on the riveting tool moveably relative to the cap ( 1 ) and is separable from the cap ( 1 ) before withdrawing the cap ( 1 ) from the rivet head ( 36 ) in order to accelerate the cooling, and wherein means ( 11 , 18 , 19 , 23 , 42 , 45 ) are provided for generating a force acting between the heating element ( 3 ) and the cap ( 1 ) in the course of separating the heating element ( 3 ) form the cap ( 1 ), which force retains the cap ( 1 ) in a stationary manner on one of objects ( 30 , 32 ) or on the formed rivet head ( 36 ).
