The inventive elbow-shaped electric plug comprises first ( 7 ) and second ( 6 ) cylindrical hollow bodies which are fixed to each other and form an angle. The end ( 2 ) of the first body ( 7 ) closed by a plug ( 3 ) is arranged on the end ( 1 ) of the second body ( 6 ), thereby defining a continuous channel between the free ends ( 8, 12 ) of two bodies ( 6, 7 ). The first body ( 7 ) comprises a demountable contact unit ( 5, 11 ). Said electric plug also comprises a cylindrical coaxial cage ( 4 ) arranged in the first body ( 7 ) in such a way that it maintains in the position the demountable contact unit ( 5, 11 ). The cage ( 4 ) is also provided with a recess ( 23 ) embodied on the longitudinal wall thereof and disposed on the side of the free end ( 12 ) of the second cylindrical body ( 6 ).
