Abstract: The assembly comprises: a car radio with a housing and a removable half front plate; a mounting sheath; means for securing the housing in the sheath; and means for unlocking the housing, said means comprising a tool suitable for being inserted in at least two orifices formed in the front face of the housing. These two orifices are formed in a central zone of the housing that is hidden by the front plate when it is mounted on the housing, and that is visible when the front plate is separated from the housing. The assembly has essentially no peripheral cover fitted thereto. The U-shaped tool makes it easy to extract the car radio using one hand in a single movement.

Abstract: The appliance comprises a casing, a removable front plate, an electrical connector, and mechanical means for assembling the front plate on the casing and for fastening it thereto. The mechanical means comprise, at a first end, means that form a separable hinge comprising at least one pair of respective magnetic elements such as permanent magnets disposed in the region of the connector and facing one another on the casing and the front plate, and the opposite end, means for locking the front plate to the casing. Mechanical coupling of the front plate on the casing at the location of the separable magnetic hinge results solely from the mutual attraction of the facing magnetic elements.

Abstract: The kit comprises a helmet unit with a microphone, earpieces, circuits for processing and amplifying an audio signal, and for coupling with a remote telephone. A self-contained wireless remote control is releasably fittable on the handlebar. The remote control is in the form of a resilient clamp having two movable branches united by a hinge provided with resilient return means enabling it to be placed around the handlebar. The resilient return means then urge the two branches to clamp onto the handlebar in order to hold the device close to the fingers of the user who can thus access the various function keys of the remote control.
