Abstract
A control arrangement is of the type comprising a control transmission chain which includes a cable (10), an actuating member such as a pedal (12) connected to one end (14) of the cable, and possibly a system of levers interposed between the other end (18) of the cable and a receiving member (28) such as a friction clutch, the flexible sheath being anchored in the vicinity of one of its ends (34) to a fixed part of a support structure (13). The end portion (36, 48) of said sheath in the vicinity of its other end (37) is mounted with the possibility of axial movement in a fixed support (38) which is fixed with respect to said support structure. A device (40) for momentary blocking of said axial movement is interposed between said end portion (36, 48) of the sheath and said fixed support (38), the blocking device (40) comprising a control member (74, 42) coupled to a point on said control transmission chain.
