The invention relates to an aid for assembly of several pipe connections of sanitary appliances, fittings and the like. According to the preamble of Claim 1.

A well-known assembly jig consists of a number of levels Plate. For the use of this assembly jig these completely penetrating pipe end parts are necessary, each of which must have a collar at a distance from their ends. One screwed into the pipe connection The assembly plug has no effect on its holder on the assembly jig (CH-PS 192 055).

Another known assembly jig also has a substantially flat plate, which in the area the distance hole each has an octagonal shape. Here, too, the pipe end parts enforce the Assembly jig, and the octagonal shape is used to accommodate one arranged on the pipe end part octagonal collar in such a way that the pipe end part is received secured against turning. Of the The pipe end part is secured by a nut screwed onto it and by the octagonal collar of the Assembly jig held (US-PS 21 40 848).

A mounting plug is also known which has a multiple step, the smallest step forms a threaded part which is in a pipe end a <> <> is screwable. The other stages serve no special purpose (DE-GM 19 31747).

Furthermore, the arrangement of a surrounding edge is known in an assembly jig (DE-GM 18 590).

The object of the invention is to securely hold the pipe connections on the assembly jig. This object is achieved according to the invention by the features in the connection part of claim 1. The pipe end butt abuts the collar of the assembly jig _{and only} partially engages in it.

Fig. 5 shows a longitudinal section through an assembly jig in the installed state.

. . ^Dic jig has a emstuckigen teachings ^kor P ^he f ^{ra 's.} lost part is made compact. The teaching body 1 has two spacer holes 2 and 3, a ' ^{e are} each surrounded by an edge 4. The spacer hole is stepped in such a way that a collar 5 protrudes into the hole. The edges 4 of the two distance holes 2 and 3 are connected to edges 6 and 7 which delimit the middle part 8 between the two distance holes 2 and 3. In this two holes 9 and 10 are provided, each of which is used to receive a fastening member, not shown. In the installed state, the teaching body I is connected to a building wall by means of fastening means penetrating its holes 9 and 10 and is plastered over as a lost part. The gauge body 1 fastened to the wall is used to fix pipe connections 11 which engage in its spacer holes 2, 3 and are located on the respective collar 5.

A hollow assembly plug 12 which is stepped three times on its outside and whose smallest step is designed as a conical threaded part 13 is used to seal off a pipe connection ti. which is screwed into the pipe. The threaded part 13 is followed by a contact shoulder 14 which, in the installed state ^1, rests tightly on the end face of the pipe connection II. A contact shoulder 15 attached to the assembly plug 12 is provided for the installation on the outside of the collar 5. In the installed state, the teaching body 1 sits with only slight axial play on the step 14 that forms the contact shoulder.

On the opposite side of the federal 5 is in the built-up state according to FIG. 5 of the Stop schullcr 14 protruding edge of the pipe connection Il. The assembly plug 12 has a ring fit conically widened I liilscntcil 16. In the area of the stepped part read assembly plug 12 See a hexagon socket as a means of attack 17 for a fastening tool; a slot for the engagement of a screwdriver can also be provided.
