PCT No. PCT/EP87/00023 Sec. 371 Date Sep. 29, 1987 Sec. 102(e) Date Sep. 29, 1987 PCT Filed Jan. 17, 1987 PCT Pub. No. WO87/04849 PCT Pub. Date Aug. 13, 1987.In order to connect the case parts (10, 12) of several potentiometer planes, a heat-shrinkable sheath (36) is used. On the outer faces (18, 20) recesses are provided along the contact faces (14, 16), between which recesses a connecting bead (30) is formed. The bead has a knurled edge (34). A heat-shrinkable sheath (36) is tightly applied, after heating and shrinking, to the bead (30), thus connecting the case parts (10, 12) in an axial and angular manner.
