Bolt housing which - comprises a bolt that can- be operated with a handle, said bolt being able to function both as a latch-bolt and as a dead bolt, wherein the bolt comprises a bolt head portion at a first end and a bolt tail portion at a second end, and the bolt can be in a first terminal position wherein the bolt head of the bolt head portion is brought maximally outside the bolt housing and in a second terminal position wherein the bolt head is brought maximally within the bolt housing, wherein the bolt housing - comprises a first organ for the pushing of the bolt head in a direction from the second terminal position towards the first terminal position; and - comprises an abutment which abutment - can be in a first position of the abutment wherein the bolt can be moved from the first position of the bolt to the second position of the bolt; and - can be in a second position of the abutment wherein the bolt can not be moved from the first position of the bolt to the second position of the bolt; wherein the bolt housing is designed for keeping the abutment in the first position of the abutment when the abutment is in the first state and for the keeping in the second position of the abutment when the abutment is in the second state; and the bolt housing further has a coupling-decoupling organ for moving the abutment from the first position of the abutment to the second position of the abutment and vice versa; and wherein the bolt is provided with the abutment and the bolt housing has a second organ that has a contact area for an abutment, which contact area follows a trajectory by movement of the second organ; wherein - in the first position of the abutment, the abutment is in the trajectory of the contact area of the second organ and the contact area of the second organ can engage the abutment so as to be able to lead the bolt in the direction from the first position of the bolt to the second position of the bolt; and - in a second position of the abutment the abutment lies outside the trajectory of the contact area and the second organ can not engage the abutment as a result of which the bolt can hot be taken along by the second organ; and the coupling-decoupling organ and the bolt tail portion engage each other via a directionally co-moving guide, comprising a cam and a recess for the cam which allows the abutment to be moved from the first position of the abutment to the second position of the abutment and back again, characterized in that the bolt head portion and the bolt tail portion are unmovable with respect to each other. - comprises a bolt that can- be operated with a handle, said bolt being able to function both as a latch-bolt and as a dead bolt, wherein the bolt comprises a bolt head portion at a first end and a bolt tail portion at a second end, and the bolt can be in a first terminal position wherein the bolt head of the bolt head portion is brought maximally outside the bolt housing and in a second terminal position wherein the bolt head is brought maximally within the bolt housing, wherein the bolt housing - comprises a first organ for the pushing of the bolt head in a direction from the second terminal position towards the first terminal position; and - comprises an abutment which abutment - can be in a first position of the abutment wherein the bolt can be moved from the first position of the bolt to the second position of the bolt; and - can be in a second position of the abutment wherein the bolt can not be moved from the first position of the bolt to the second position of the bolt; - can be in a first position of the abutment wherein the bolt can be moved from the first position of the bolt to the second position of the bolt; and - can be in a second position of the abutment wherein the bolt can not be moved from the first position of the bolt to the second position of the bolt; - in the first position of the abutment, the abutment is in the trajectory of the contact area of the second organ and the contact area of the second organ can engage the abutment so as to be able to lead the bolt in the direction from the first position of the bolt to the second position of the bolt; and - in a second position of the abutment the abutment lies outside the trajectory of the contact area and the second organ can not engage the abutment as a result of which the bolt can hot be taken along by the second organ;
