Furthermore, the present invention relates to a sash profile for forming a sash frame for a window or door, wherein the sash profile includes a glass rebate for receiving a surface element, in particular insulating glass, at its end face and, on its side opposite the glass rebate, a stop with a sealing groove for a stop seal, as well as a connection comprising at least one such sash and an additional element.

[0002] Such sashes for windows and doors, sash profiles for forming window and door sashes, and such sash-encompassing connections are widely known in the prior art. For example, DE 20 2008 009 721 U1 describes such a sash-encompassing connection using the example of a mullion connection, in which an additional element designed as a mullion strip rests against a stop of the sash in a corner area via a profile web. For pre-fixing, the additional element is connected to the hardware groove of the sash via a locking tab. A disadvantage of the sash and the connection encompassing it described in DE 20 2008 009 721 U1 is that the additional element, designed as a mullion strip, is not fully screwed in place, making tightening more difficult because the mullion strip can easily slip when the fastening screw is driven in.

[0003] This is where the present invention comes in, which aims to provide a wing that at least partially overcomes the disadvantages of the prior art. In particular, the final attachment of an additional element to the wing according to the invention should be easier.

[0004] These and other problems are solved by a sash for a window or door having the features of claim 1, a sash profile having the features of claim 5, and a connection having the features of claim 9. Preferred embodiments of the present invention are described in the respective dependent claims.
