The manual gas tap for a cooking appliance is of the type with a conical plug (3) for regulating the outlet gas flow (G), accommodated in a central housing (2a) in the tap body, and has a rotary actuating shaft (4) coupled to the conical regulating plug (3), and a tap cover (5) covering said central housing (2a). The rotary shaft (4) is provided with a transverse pin (6) for rotation thereof from an initial rotation locking position (7) corresponding to the gas supply “OFF”, to two other spaced positions corresponding to the maximum and minimum gas flows. The tap cover (5) is a tubular bushing shaped and comprises a sealing base (5c) with a sliding surface (11) in the form of a circular arc segment (A) provided with a series of indentations (12), which are in friction contact with the transverse pin (6) and produce a tactile and/or acoustic indication of shaft (4) rotation and tap (1) opening.
