Casement arrangement having a casement of a window or door and method for the frontal installation of a fitting part in a casement

A casement arrangement comprising a casement of a window or door, with a frame profile of the casement, said frame profile having a C-shaped casement groove in a rebate, and comprising a fitting part with a main body insertable into the casement groove;

• further comprising a connector releasably connectable to the main body of the fitting part, wherein the casement groove has a first groove limb and a first groove portion and, located opposite, a second groove limb and a second groove portion;
• wherein the fitting part has an elongate main body having a front side and a rear side with on opposite longitudinal sides, a first peripheral region to engage behind the first groove limb of the casement groove and a second peripheral region to engage behind the second groove limb of the casement groove, wherein the main body of the fitting part is configured in a mirror-symmetrical manner in relation to its longitudinal center axis;
• and wherein a distance of a groove bottom of the first groove portion or second groove portion from a free end of a groove limb of an opposite groove portion is greater than a width of said at least one fitting part, such that said at least one fitting part is pivotable into the casement groove with the peripheral regions inserted into the groove portions, and wherein the connector comprises a connection body having a rear side and a front side;
• and further comprising at least one foot, on the rear side of the connection body, having at least one engagement protrusion to engage a groove of the fitting part and further comprising a protrusion, tapering in a wedge-shaped manner towards its free end in a longitudinal direction or on its underside, the connection body being arrangeable between two angled limbs of the fitting part on at least one end side of the connection body and comprises a screw-connection through-opening to receive a punching screw to fix the connector to the fitting part;
• and wherein the connection body is configured in a mirror-symmetrical manner in relation to its longitudinal center axis with regard to the screw-connection.
