Awning housing for a cassette awning, comprising - an upper roof section with a front edge leg pointing in the direction of projection of the awning to terminate with a front profile retracted into the awning housing, - a receiving area for a fabric roller with a fabric wrap, - a lower bottom section, and - at least one insertion slider at the front edge leg for sliding guidance of the awning fabric and/or abutment of the retracted front profile, characterized by - a flat, downwardly open receiving channel at the front edge leg for the at least one insertion slider, which receiving channel has lateral undercuts (14, 15) facing one another at a distance for anchoring the insertion slider, wherein = the insertion slider has a plate-shaped, elastic bending zone between respective engagement edges (22, 23) facing away from each other for respective engagement in the undercuts (14, 15), = the distance between the engagement edges (22, 23) of the insertion slider in the unbent state is greater than the distance between the undercuts (14, 15), = for mounting the insertion slider in the receiving channel, the insertion slider can be inserted into the undercuts (14, 15) with elastic deflection of the bending zone pointing away from the receiving channel, and = the bending zone can then be brought into a deflection bent into the receiving channel in the manner of over-dead-centre kinematics. - an upper roof section with a front edge leg pointing in the direction of projection of the awning to terminate with a front profile retracted into the awning housing, - a receiving area for a fabric roller with a fabric wrap, - a lower bottom section, and - at least one insertion slider at the front edge leg for sliding guidance of the awning fabric and/or abutment of the retracted front profile, characterized by - a flat, downwardly open receiving channel at the front edge leg for the at least one insertion slider, which receiving channel has lateral undercuts (14, 15) facing one another at a distance for anchoring the insertion slider, wherein = the insertion slider has a plate-shaped, elastic bending zone between respective engagement edges (22, 23) facing away from each other for respective engagement in the undercuts (14, 15), = the distance between the engagement edges (22, 23) of the insertion slider in the unbent state is greater than the distance between the undercuts (14, 15), = for mounting the insertion slider in the receiving channel, the insertion slider can be inserted into the undercuts (14, 15) with elastic deflection of the bending zone pointing away from the receiving channel, and = the bending zone can then be brought into a deflection bent into the receiving channel in the manner of over-dead-centre kinematics. = the insertion slider has a plate-shaped, elastic bending zone between respective engagement edges (22, 23) facing away from each other for respective engagement in the undercuts (14, 15), = the distance between the engagement edges (22, 23) of the insertion slider in the unbent state is greater than the distance between the undercuts (14, 15), = for mounting the insertion slider in the receiving channel, the insertion slider can be inserted into the undercuts (14, 15) with elastic deflection of the bending zone pointing away from the receiving channel, and = the bending zone can then be brought into a deflection bent into the receiving channel in the manner of over-dead-centre kinematics.
