The locking hooks 104 extend are within the shell 80 , A ring wall 108 the holding receptacle 92 of the top 80 is at one to the mounting plate 82 pointing forehead 110 Radially downgraded from the inside diameter to the outside, bringing a ring receiver 112 is designed. In this one is on the inside 102 the mounting plate 82 trained centering ring 114 when assembling the shell 80 and the mounting plate 82 submersible. An inner diameter of the centering ring 114 corresponds approximately to the diameter of the holding receptacle 92 , where the LED light 2 in composite holding device 4 in the centering ring 114 dips to a disc-shaped bottom plate 116 made of plastic, in which the permanent magnet 94 is integrated. The bottom plate 116 and a bottom 118 the mounting plate 82 out 6 form an approximately flat surface.

The upper part is mounted 80 and the mounting plate 82 by removing the centering ring 114 in the ring holder 112 dips to the stop and the upper part 80 relative to the mounting plate 82 twisted around the longitudinal axis until the locking hooks 104 and the bayonet hooks 106 behind engage and the latter rest on a stop, not shown, in the direction of rotation.
