The top sides shown are hats 12 of rectangular cross-section, so that when the side parts according to Pig '. 5 are unfolded, folded up, the result is a rectangular interior, the height of which corresponds to the height of the central part 10, but the cavity has a greater width on both sides of the central part 10 and forms slots there into which the shaft parts 3 of the contact organs are placed. According to Piguren 1 and Φ the hats 12 are designed so that rectangular Abeätse 23 result on the lower edge, the paragraphs 23 according to Pig adapted 'so that the contact organs are fixed with regard to longitudinal mobility «

Behind the hats 13 the side parts have one Planschabsehnitt 17, which is in front of the hat 16 of the rear end of the Housing part is arranged. Behind the hat 16, the side parts have a protruding part 14 'which goes inwards and backwards slopes obliquely. The projection 14 serves the purpose that a Locking ring 8 can be placed resiliently, so that the hingedly interconnected side parts 9 with respect to the inner Middle part 10 are kept closed. The tapered end 15 facilitates the steeking of the integral part 8 on the housing part and leaves the slotted hanging part spring apart as a result of the wedge effect.

In front of the side parts 9, the housing part has a relatively rigid cable 19 »which forms a channel from the underside of the middle part 10 to the top and for this purpose two opposite one another: Has lying side walls, two slots 20 being formed for receiving © the shaft parts 3 of the contact organs 1.
