The first and second metallic side sections each include a side wall for connecting to a glass pane and a retaining arm, which protrudes into the intermediate space, and the retaining arm forms an assembly groove with the side wall, which groove runs substantially parallel to the side wall. The polymeric connecting piece is U-shaped and its two legs are inserted into the assembly grooves of the two metallic side sections. ## Claims ### Claim 1 A spacer for insulating glass units, comprising: a U-shaped main body extending in a longitudinal direction including a first metallic side section, a second metallic side section arranged parallel thereto, a polymeric connecting piece extending in a transverse direction, which connects the first and second metallic side sections and forms a lower limit of the main body, and an intermediate space arranged above the polymeric connecting piece between the first and second metallic side sections, wherein the first and second metallic side sections each include at least one side wall for connecting to a glass pane and a retaining arm, which protrudes into the intermediate space, and the retaining arm forms an assembly groove with the side wall, which groove runs substantially parallel to the side wall, the polymeric connecting piece is U-shaped and includes two legs that are inserted into the assembly grooves of the first and second metallic side sections. ### Claim 2 (depends on 1) The spacer according to claim 1, wherein the first and second metallic side sections each have case a fixing projection, which surrounds a corner region of the U-shaped polymeric connecting piece and whereby the polymeric connecting piece is fixed in the assembly groove. ### Claim 3 (depends on 1) The spacer according to claim 1, wherein the polymeric connecting piece includes at least one moisture-proof barrier. ### Claim 4 (depends on 1) The spacer according to claim 1, wherein an adhesion-promoter layer is arranged on the side of the polymeric connecting piece facing away from the intermediate space. ### Claim 5 (depends on 1) The spacer according to claim 1, wherein a sealing means is provided in the assembly groove. ### Claim 6 (depends on 1) The spacer according to claim 1, wherein the first and second metallic side sections are produced by roll forming or by extrusion. ### Claim 7 (depends on 1) The spacer according to claim 1, wherein a cover film extends in the transverse direction between the first metallic side section and the second metallic side section and thus closes the intermediate space. ### Claim 8 (depends on 1) The spacer according to claim 1, wherein in the intermediate space, a desiccant is arranged. ### Claim 9 (depends on 1) The spacer according to claim 1, comprising a receiving profile for an additional pane, wherein the receiving profile is arranged between the first metallic side section and the second metallic side section and wherein the receiving profile includes a receiving groove or the additional pane, which groove extends in the longitudinal direction. ### Claim 10 (depends on 9) The spacer according to claim 9, wherein the receiving profile is implemented as a metallic receiving profile. ### Claim 11 (depends on 9) The spacer according to claim 9, wherein the polymeric connecting piece is divided by the receiving profile into a first U-shaped polymeric connecting piece and a second U-shaped polymeric connecting piece, the receiving profile has a first inner assembly groove and a second inner assembly groove, and one leg of the first U-shaped polymeric connecting piece is received in the first inner assembly groove, and one leg of the second polymeric connecting piece is received in the second inner assembly groove. ### Claim 12 (depends on 1) A method for producing a spacer according to claim 1 comprising: a) extruding or roll forming the first metallic side section and the second metallic side section, b) providing the U-shaped polymeric connecting piece, c) inserting and fastening the U-shaped polymeric connecting piece in the assembly grooves of the two metallic side sections. ### Claim 13 (depends on 1) An insulating glass unit, comprising a first pane, a second pane, a spacer according to claim 1 arranged circumferentially between the first pane and the second pane, wherein the first pane is attached to the side wall of the first metallic side section via a primary sealant, the second pane is attached to the side wall of the second metallic side section via a primary sealant, the spacer separates an inner interpane space from an outer interpane space, and a secondary sealant is arranged in the outer interpane space. ### Claim 14 (depends on 1, 13) A method for producing an insulating glass unit according to claim 13, comprising d) providing a spacer according to claim 1, e) bending the spacer to form a spacer frame, which is closed at one point, f) providing a first pane and a second pane, g) fixing the spacer between the first pane and the second pane via a primary sealant, h) pressing the pane assembly comprising the first and second panes and the spacer, and i) at least partially filling the outer interpane space with a secondary sealant. ### Claim 15 (depends on 13) A method comprising utilizing the insulating glass unit according to claim 13 as a building interior glazing, a building exterior glazing, and/or a façade glazing. ### Claim 16 (depends on 3) The spacer according to claim 3, wherein the at least one moisture-proof barrier is in the form of a metal coating, a ceramic coating, a polymer film, or a multilayer film with polymeric and metallic layers or with polymeric and ceramic layers or with polymeric, metallic, and ceramic layers. ### Claim 17 (depends on 4) The spacer according to claim 4, wherein an adhesion-promoter layer is a metal-containing thin film or a ceramic thin film. ### Claim 18 (depends on 5) The spacer according to claim 5, wherein a sealing means is a butyl cord. ### Claim 19 (depends on 7) The spacer according to claim 7, wherein the cover film at least partially surrounds the first and second metallic side sections in the upper region. ### Claim 20 (depends on 8) The spacer according to claim 8, wherein the desiccant has a continuous desiccant body in the form of a strip or flexible tube.
