A diffusion-tight joint (30) between ends of prefabricated spacers (10) that support a diffusion barrier (3) on the spacer outer face is achieved in that a tongue (9) is formed from the diffusion barrier (3) at an end of two spacers (10) that abut each other at a joint (30), the tongue protruding ov

A diffusion-tight joint (30) between ends of prefabricated spacers (10) that support a diffusion barrier (3) on the spacer outer face is achieved in that a tongue (9) is formed from the diffusion barrier (3) at an end of two spacers (10) that abut each other at a joint (30), the tongue protruding over the end. The tongue (9) is fixed to the outer face of the diffusion barrier (3) of the other end of the spacer (10) using an adhesive application (13) so that an overlapping of the diffusion barriers (3) of both ends is achieved. The formation of the joint can be formed in the corner region of prefabricated spacer frames (10) or in straight regions of spacers (10), thus wherever ends of spacers (10) that are prefabricated abut each other.

1. A system, comprising: a joint; anda plurality of prefabricated spacers for a plurality of insulating glass plates, the joint being disposed between ends of abutting ones of the prefabricated spacers, the spacers having a diffusion barrier that is a metal strip on an outer side facing toward the joint disposed between the glass plates, a protruding tongue being integral with and protruding from the diffusion barrier on one end of a first one of the abutting spacers the protruding tongue being bonded to an outside of the diffusion barrier at one end of another one of the abutting spacers. 2. The system according to claim 1, wherein the bonding is formed with an adhesive based on butyl rubber. 3. The system according to claim 1, wherein the joint is disposed in a corner between abutting spacers, the tongue lapping over by being bent onto the diffusion barrier at the end of the other spacer that abuts the first spacer in the corner. 4. The system according to claim 1, wherein the joint is disposed in the vicinity of a straight section of the abutting spacers, the faces of the abutting spacers being oriented at a 90° angle to a lengthwise extension of the abutting spacers. 5. The system according to claim 1, wherein the joint is formed in the vicinity of a straight section of the abutting spacers, the faces of the abutting spacers being oriented at an acute angle to a lengthwise extension of the abutting spacers. 6. A method, comprising: producing the joint between the ends of the spacers according to claim 1, producing the joint between the ends of the spacers including removing, on the one end of the first spacer, a plastic core of the first spacer and coatings provided on the sides of the plastic core and leaving a part of the diffusion barrier, of the first spacer, that protrudes as a tongue, andattaching the tongue of the diffusion barrier of the first spacer to the outside of the diffusion barrier of an adjacent end of the other abutting spacer. 7. The method according to claim 6, wherein the protruding tongue of the diffusion barrier of the first spacer is attached to the outside of the diffusion barrier of the adjacent end of the other spacer with an adhesive. 8. The method according to claim 6, further comprising: putting the protruding tongue of the diffusion barrier of the first spacer in place by bending the protruding tongue at the diffusion barrier of the end of the other spacer that is at an angle to the end of the first spacer, when the joint is formed in a corner between the abutting spacers. 9. The method according to claim 7, further comprising: putting the protruding tongue of the diffusion barrier of the first spacer in place by bending the protruding tongue at the diffusion barrier of the end of the other spacer that is at an angle to the end of the first spacer, when the joint is formed in a corner between the abutting spacers.
