ABSTRACT:
A device for attaching an object to a wall comprises a body with a cylindrical head centrally disposed on a base. The head incorporates longitudinal elastic members terminating in hooks. These are adapted to engage on the edges of an opening in the wall into which the head is inserted. A clamping ring mounted on the head is movable along its length. A spring is disposed between the base of the body and the clamping ring. The force exerted by this spring is transmitted to the wall so as to lock the hooks on to the edges of the opening. Cooperating guide means on the clamping ring and on the body are adapted to guide the clamping ring as it moves along the head, simultaneously rotating. Cooperating locking means on the body and on the clamping ring are adapted to lock the clamping ring in a bottom position on the head. The cooperation of the locking means defines a stable armed position of the device, in which the hooks are spaced from the clamping ring to enable the head to be inserted into the opening in the wall. These locking means are then released by pressure on the clamping ring.
