A pair of tape heaters 11 are arranged respectively on opposite sides of at least one line and held to the corresponding coupling members by a plurality of clips 12. Each of the clips 12 comprises a pair of side walls 13 opposed to each other as spaced apart by a predetermined distance, and a connecting wall 14 interconnecting the pair of side walls 13 at an intermediate portion of the height thereof so as to move lower portions of the side walls 13 away from each other when upper portions of the side walls 13 are subjected to a force acting to move the upper portions toward each other and to restore the side walls 13 to the original state when the force is removed.

Lower members (31,33) each have a bolt bore (107) comprising a large-diameter portion (107a) larger than the head (110a) of a bolt (110) in diameter, and a small diameter portion (107b) extending downward from the large-diameter portion (107a) with a stepped portion (107c) formed therebetween and having a diameter intermediate between the diameter of the bold head (110a) and the diameter of the shank (110b) of the bolt (110). The small-diameter portion (107b) of the bolt bore (107) has fitted therein a hollow cylindrical spacer (111) with an inside diameter larger than the diameter of the bolt shank (110b). The spacer (111) has a lower end supported by a support member (108) and an upper end positioned in the large-diameter portion (107a). A hollow cylindrical elastic member (112) is interposed between the bolt head (110a) and the stepped portion (107c) for biasing the lower member (31,33) toward the support member (108).

A connecting layer for interconnecting fluid control devices in series and in parallel comprises an upper connecting layer 4 and a lower connecting layer 5. The upper connecting layer 4 is provided by parallel rows each comprising block couplings 41, 42, 43, 44 arranged longitudinally of the apparatus, each of the block couplings having a longitudinal channel 61 for interconnecting the adjacent fluid control devices in the row and a through channel 62 communicating with the fluid control device. The lower connecting layer 5 is provided by block coupling 56, 57, 58 each having a lateral channel 64 for interconnecting the through channels 62 of the block couplings 41, 42, 43, 44 of the upper connecting layer 4 which are arranged laterally and by block couplings 51 each adapted to cause the through channel 62 of the block coupling 41, 43, 44 of the upper connecting layer 4 to communicate with an inlet-side or outlet-side coupling 52, 53. The couplings 51,56, 57, 58 of the lower connecting layer 5 are attached to a base plate 2 with screws from above, and the couplings 41, 42, 43, 44 of the upper connecting layer 4 are attached to the couplings 51, 56, 57, 58 of the lower connecting layer 5 with screws form above.

An annular recess is formed in an inner periphery defining a bolt shank bore (114) and has fitted therein an annular elastic member (115) having elasticity radially thereof and having an inside diameter smaller than the outside diameter of the shank of a bolt (113). The shank bore (114) has at an intermediate part thereof a stepped portion so as to give an increased diameter to a bore portion from the intermediate part to one end of the bore, and a hollow cylindrical member for preventing the elastic member from slipping out is inserted in the shank bore (114) from the bore end so as to form a clearance between the stepped portion and the preventing member, whereby the annular recess is formed.
