A locating mechanism in which a pin or bolt is slidably accommodated in a bore for movement between a locking position and an unlocking position. The pin has a locking projection at one end and is provided with means for preventing rotation of the pin within the bore and hence ensuring that the locking projection is at all times oriented in the desired direction. The means is also operable to limit the extent by which the pin or bolt may slide longitudinally within the bore and, hence, serves to control the degree of travel of the locking projection. The means is a C-spring which extends radially outwardly from the pin or bolt and is seated in a registering recess which opens into the bore. In this manner the C-spring will prevent rotation of the pin within the bore and will permit longitudinal displacement of the pin in the bore by an extent corresponding to the permissible flexing of the C-spring until such time as the limbs of the C-spring come together into abutting relationship.
