Abstract
A safety cap, particularly for cooling liquid circuits of i.c. engines for motorvehicles, comprising an inner cover to be screwed onto a circuit filler and bearing a body axially and sealingly engageable within the filler. The body is hollow and carries a thermostatic actuator, and the inner cover is substantially completely surrounded by an outer cover which is movable, by means of the thermostatic actuator, from a torsionally coupled position to a torsionally uncoupled position relative to the inner cover.
