Abstract The protective device prevents overheating, in particular by fire, of individual or batteries of pressure vessels (10) of length (1) equal to at least 1,5 m, employed for storage and/or transportation of gases under high pressure. The essentially cylindrical pressure vessels (10) have at least one closure cap (14) with a valve (18) or a closure plug. Mounted on one closure cap (14) is a pressure pipe (24) which communicates with the interior of the pressure vessel (10), and is fitted with a controllable venting valve (58) that under normal conditions closes off the pressure pipe (24) or a common pressure pipe (56) and has a venting pipe (60) which terminates outwith the region of the pressure vessel/vessels (10). Temperature sensitive actuating means are provided in the axial direction (A) of the pressure vessel/vessels (10) a spacing (a) apart and connected to the venting valve (58). These means can individually actuate the venting valve (58) should overheating occur. (figure 1)
