A coupling head for pressure medium lines of pressure medium break units in vehicles. The coupling head has a valve body which is fixedly disposed in a main body of the coupling head. During the connection of the coupling head with a cooperating coupling head, the actuating member is moved, whereby the valve of the coupling head is opened for the passage of pressure medium. In the closure position, the actuating member rests against an abutment, in the vicinity of which is fixedly disposed a sealing element, at least a portion of the periphery of which is braced against transverse deformation. Due to the fixed valve body, the coupling head has a structurally simple design and can be easily assembled. A sealing element acts as a static seal, and is subjected to only slight wear. Due to the fact that the sealing element is braced against transverse deformation, an unduly or unacceptably great deformation of the sealing element is reliably prevented.
