A muntin assembly for an associated window glass. The muntin assembly includes a first muntin bar that defines a first pocket and includes a first cleat. The muntin assembly also includes a second muntin bar that defines a second pocket and includes a second cleat. The muntin assembly also includes a clip disposed in the first pocket and the second pocket so as to hook the first muntin bar and the second muntin bar together in an overlapping arrangement. Further, the clip momentarily deforms to accept receipt of the first cleat and the second cleat.

A clip for supporting a muntin grid, a muntin grid, and a method of assembly is disclosed herein. The clip includes coupled together lateral and longitudinal members, each supporting bosses, and first and second arms respectively. The clip for coupling to the first and second muntin bars via first and second notches in the respective muntin bars. The muntin bars are formed by pre-notching and then roll forming, wherein the bosses support the first and second muntin bars when the clip is coupling the first muntin bar to the second muntin bar.

A connecting element for connecting at least two profile elements, wherein the connecting element is rotatable about an axis of rotation to produce a clamping force, wherein the connecting element has at least one first connecting section and at least one second connecting section, which are each designed to be received in one of the profile elements, wherein the first connecting section has at least one first clamping face, wherein the at least one first clamping face has a predetermined clamping contour, wherein the second connecting section has at least one second clamping face, wherein the first clamping face faces the second connecting section and the second clamping face faces the first connecting section, wherein the first connecting section and the second connecting section are formed such that the profile elements connected by the connecting element extend obliquely relative to each other or crosswise.

The invention relates to a connecting element (10) for connecting at least two profile elements (100, 200), wherein the connecting element (10) is rotatable about an axis of rotation (D) to produce a clamping force, wherein the connecting element (10) has at least one first connecting section (12) and at least one second connecting section (14), which are each designed to be received in one of the profile elements (100, 200), wherein the first connecting section (12) has at least one first clamping face (20, 22), wherein the at least one first clamping face (20, 22) is designed with a predetermined clamping contour (KK.sub.1), wherein the second connecting section (14) has at least one second clamping face (24, 74), wherein the first clamping face (20, 22) faces the second connecting section (14) and the second clamping face (24, 74) faces the first connecting section (12), wherein the first connecting section (12) and the second connecting section (14) are formed in such a way that the profile elements (100, 200) connected by means of the connecting element (10) extend obliquely relative to each other or crosswise.

A clip for supporting a muntin grid, a muntin grid, and a method of assembly is disclosed herein. The clip includes coupled together lateral and longitudinal members, each supporting bosses, and first and second arms respectively.
