Abstract: A security apparatus for preventing theft and/or tampering of an equipment or a part of this equipment, comprises a base member having a front wall, two opposite side walls and a rear wall. First and second elongated bent rods each include a first end section secured to the rear wall, a second end section secured to one of the two opposite side walls, a third rod section extending along a rear face of the equipment, and a fourth rod section extending along a top face of the equipment. The first and second elongated bent rods further comprise respective fifth rod sections extending along two opposite side faces of the equipment, respectively. A movement-restraining member extends along a front face of the equipment, this movement-restraining member comprising a key or combination lock for removably locking this movement-restraining member to the base member to thereby lock the equipment in the security apparatus.
