Abstract

A locking pin, in particular for the securing of shift positions of a shift linkage in automobile transmissions, comprises a hollow cylindrical shaft portion (1) which is drawn from thin-walled sheet metal and closed at one end by a bottom (2). This bottom (2) projects radially beyond the shaft portion (1). A locking element (3) projecting out of the shaft portion (1) at the open end thereof is guided longitudinally displaceable in the shaft portion (1), retained secure against loss und pre-tensioned in the locking direction by a spring (4). To obtain a locking pin which is cost-effective in manufacturing and easily dismountable, a diameter enlargement (7) serving as a stop is provided at a pre-determined distance both from the open end of the shaft portion (1) and from the bottom (2).
