Abstract

A fastening device for fixing a body on a wall or ceiling surface, comprising at least one fastening member mountable on said holding surface and the body to be detachably fixed having two elongated mounting flanges which are parallelly disposed and project in the same direction transversely to their length for being engaged in fastened position of the body by the member, in which position one flange is lengthwise in contact with the holding surface, whereby the fastening member is substantially covered by the body and comprises at least one lock pawl resiliently arranged for locking the body in fastened position, between the fastened body and the holding surface being provided free space for the pawl to allow its resilient withdrawel from locking position.

Claims

1. A fastening device for fixing a body on a wall or ceiling surface, comprising at least one fastening member mountable on said holding surface, said member having two spaced engaging means which are interconnected and transversely project in the same direction, and at least one pawl extending from the one engaging mean transversely thereto towards the other engaging mean in substantially opposite direction to said direction of the projection of said engaging means, said pawl being resiliently movable transversely to its extending direction and having a nose projecting in the direction of the spring tension, and on the body to be fixed by means of said member two spaced elongated flanges transversely projecting in the extending direction of said pawl, whereby in fixed position of said body said flanges being engaged by said engaging means and said body being locked by said nose of said pawl.

2. A fastening device as claimed in claim 1, wherein said engaging means of said fastening member are pArallel ledges adapted to engage said flanges being parallelly formed on said body, and said pawl is a resilient tongue said locking nose of which projects in locking position between said flanges.

3. A fastening device as claimed in claim 1, wherein the free end of said pawl projects beyond said locking nose and at least as far as the outer edge of said other engaging mean.

4. A fastening device as claimed in claim 1, wherein said fastening member has two parallel ledges and two resilient pawl tongues between which said ledges are connected by a traverse portion by which said member is mountable on said holding surface.

5. A fastening device as claimed in claim 1, wherein said fastening member consists of one piece only made of synthetic resin.

6. A fastening device as claimed in claim 1, wherein said body is a rail having two parallel flanges and adjacent to one of said flanges a longitudinal edge destined, in fixed condition of said body, to be in contact with said holding surface and adjacent to the other of said flanges a longitudinal edge destined in said condition to be in contact with a traverse portion connecting said engaging means of said fastening member.
