1. Electric connecting device for electrically controlled, so called pilot valves (21-25) connected to a corresponding number of valves (1-5) in a modular valve array, wherein each pilot valve has equally placed contact pins (26,27,28), which are connected to a common connecting cable (29) with a plurality of conductors over an electric connecting module (30),
c h a r a c t e r i z e d in

- that each connecting module (30) essentially consists of a coupling plate (32) provided with on the one hand contact sockets (33,34,35) dimensioned and arranged for connection to said contact pins (26,27,28) of the respective pilot valve (21), and on the other hand a multipolar contact
means (37) being connectable to a corresponding cable
contact means (38) which is connected to the conductors of the common connecting cable (29);

- that said connecting cable (29) comprises series-connected flexible portions (29a, 29b, 29c, etc) between the connecting modules (30);

- that said coupling plate (32) is provided with an array of controllable electric connections (36), in particular contact bridges, for the desired connection between said multipolar cable contact means (37) and said contact
sockets (33,34,35), whereby the respective connecting
module (30) is programmable for achieving electric
connection between the contact pins (26,27,28) of the
associated pilot valve and desired conductors of the
common, flexible connecting cable (29).

2. Connecting device according to claim 1, c h a r a c t e r i z e d in that said flexible connecting cable is constituted of a flat cable (29).

3. Connecting device according to claim 2, c h a r a c t e r i z e d in that the ends of two adjoining flat cable portions are jointly connected into said cable contact means (38).

4. Connecting device according to claim 3, c h a r a c t e r -i z e d in that said cable contact means is constituted by a longitudinal, relatively flat socket contact means (38) extending along the width of the flat cable, whereas said multipolar contact means is constituted by a corresponding pin contact means (37) attached to said coupling plate (32).

5. Connecting device according to any of the claims 1-4, c h a r a c t e r i z e d in that said coupling plate is constituted by a circuit card (32) with components, including said contact sockets (33,34,35), multipolar contact means (37) and electric connections (36) attached thereto.

6. Connecting device according to claims 4 and 5,
c h a r a c t e r i z e d in that said pin contact means (37) is angled in such a way that the associated socket contact means (38) and the ends of the flat cable portions (29a, 29b) connected thereto lie parallel to the circuit card (32) .

7. Connecting device according to claim 5 or 6,
c h a r a c t e r i z e d in that said components of the circuit card include means for operational indication, e.g. a light emitting diode (39), and/or protective means, e.g.
transient protective means, e.g. a varistor (40), a zener diode or the like.

8. Connecting device according to any of the preceding claims,
c h a r a c t e r i z e d in that said controllable electric
connections (36) are constituted by mechanically breakable
short- circuit sheet metal elements.

9. Connecting device according to any of the preceding claims,
c h a r a c t e r i z e d in that said contact pins (26,27,28) of the respective pilot valve (21) together with the associated coupling plate (32) and contact means are contained in an open- 10 able, preferably two-part protective housing Ola, 31b) with
lead-through arrangements for said connecting cable (29) .

10. Connecting device according to claims 6 and 9,
c h a r a c t e r i z e d in that the protective housing
15 Ola, 31b) iε divided into two parts and that the circuit card
(32) lies essentially in the partition plane of the protective
housing, whereby both of the flat cable portions (29a, 29b),
which are connected to said socket contact means (38), are
brought through the wall of the protective housing in the
20 partition plane, preferably between elastic seals (43,44).
