Claim 14:
15. A wall or ceiling assembly for forming attaching wall or ceiling panels to a substructure, comprising:
at least two wall or ceiling panels; and
a clip for securing the panel to the substructure;
wherein the panels each comprise a male coupling part and, on an opposite side edge of the panels, each comprise a female coupling part;
wherein the male and female coupling parts are configured such that the two panels, by means of the male and female coupling parts, can be coupled to each other in a plane and a coupled condition can be realized between the panels;
wherein the male coupling part comprises a tongue and the female coupling part comprises a groove, wherein the tongue and the groove, in the coupled condition, form a tongue-and-groove connection, which realizes a mechanical locking between the panels in a direction perpendicular to the plane of the panels;
wherein the groove is bordered by a front lip and a rear lip;
wherein the male and female coupling parts each comprise a locking part, wherein the locking part of the male coupling part and the locking part of the female coupling part, in a coupled condition, realize a mechanical locking between the panels in a direction in the plane of the panels and perpendicular to the side edges;
wherein the locking part of the male coupling part is provided on the rear side of the tongue and the locking part of the female coupling part is provided on the front side of the rear lip;
wherein the front lip extends substantially parallel to the plane of the panels, and the rear lip of the groove extends substantially parallel to the front lip with a distal end of the rear lip extending parallel to the plane of the panels;
wherein at the front side of the rear lip, the rear lip is provided with a substantially flat surface extending from the locking part in a distal direction toward the distal end of the rear lip for receiving the clip;
wherein the clip comprises a front leg and a base, wherein the front leg is provided for being slid over the locking part of the rear leg, for securing the panel against a substructure;
wherein each of the locking parts defines an inclined planar section, wherein the planar sections of the locking parts contact each other in the coupled condition, wherein the locking parts lock in the direction in the plane of the panels and perpendicular to the side edges;
wherein the male and female coupling parts are respectively defined at long side edges of the panel;
wherein the panel defines short side edges perpendicular to the long side edges, and the short side edges of the panels are devoid of coupling parts;
wherein a recess is defined along a rear side of the panel at the side edge comprising the tongue and extends a depth into a thickness of the panel from a rear surface of the rear side, wherein the recess is configured and dimensioned for receiving at least part of the clip for securing the panel to the substructure.
