Abstract: A closure member restraining device 10 is provided which comprises a body mountable on a support surface, such as a wall, adjacent the closure member, a buffer arm 14 and a catch 16. The body comprises a buffer housing with a tubular sidewall 20 and an integrally moulded skirt 22 extending backwardly from the housing. The catch 16 depends from the buffer housing and automatically engages a handle formation on an opened door and restrains the door, so preventing it from closing. The buffer arm 14 is movable into and out of the buffer housing by coaxial screw or sliding movement to pre-set its position so that irrespective of the distance between the handle formation and the closure member, the buffer arm 14 abuts the closure member when the handle formation is engaged by the catch, thereby preventing movement of the closure member.
