Abstract: A removable apparatus used to cover a knob is provided that includes an inner casing and an outer casing, both of which together form a collar that surrounds a portion of the knob and in so doing mechanically decouples a rotary motion that is applied to the cover from the knob. Disposed intermediate the inner casing and the outer casing is provided a latching mechanism which secures a hinged door to the cover. Release of the latching mechanism requires a two-step procedure beginning with the simultaneous application of a sufficient vertical force applied to urge a pair of vertical slide members downward. The downward force must be maintained in order for the second step to be accomplished.

Abstract: A pipe clamp with a headed bolt for securing a pipe connection, in particular pipes of the exhaust system of a motor vehicle which are to be connected to one another, in the case of which the end of a first pipe is pushed into an axially slit end of a second pipe and, when the headed bolt is tightened, the pipe clamp, fitted on the slit pipe end, connects the two pipe ends to one another in a frictionally locking manner, is to be secured against a reduction in clamping force. For this purpose, the pipe clamp is formed of a material which has a higher coefficient of expansion than does the material of the pipes which are to be connected. The head of the headed bolt is elongated, in order to avoid impermissibly high local stressing during tightening of the pipe clamp. Due to the elongate form of the head of a headed bolt, the forces on the pipe clamp which support the tightening torque are reduced by a lengthening of the lever arm with respect to the axis of the headed bolt.
