A fastening device for fastening an earthing contact to a metallic protective tube. The fastening device includes an annular guide eyelet having an end face, a half-shell-shaped fixed clamping jaw which is integrally molded on the end face, and a loose clamping jaw configured to be clamped to the fixed clamping jaw. In an assembled state, the half-shell-shaped fixed clamping jaw and the loose clamping jaw are configured to clamp the metallic protective tube. The fastening device further includes at least one of the half-shell-shaped fixed clamping jaw and the loose clamping jaw comprising a receptacle-forming clamping jaw having an inner surface that forms a receptacle configured to receive the earthing contact.

Earthing contact fastening device

In order to reliably lock an electric plug and socket assembly ( ) including an outer part ( ) and inner part ( ) which can be coupled to the outer part, the inner part is provided with a recess ( ) into which, when the two parts are coupled, a snap-on hook means ( ) is engaged and maintained so as to act as a spring. When the plug and socket assembly ( ) is in a locked position, the snap-on hook means ( ) or each snap-on hook means is locked against radial excursion since it rests on a bushing ( ) which is axially displaceable on the outer part ( ). In the locked position, the backward pulled bush ( ) releases the snap-on hook means ( ) thereby allowing for disengagement of the outer and inner parts ( ). In order to enable the plugging of the parts ( ) when the bushing ( ) is in the locked position, the snap-on hook means ( ) is provided with two spring legs ( ) whose end cam ( ) and an inner contour ( ) running into the recess ( ) of the inner part ( ) form a guide for the two leg snap-on hook means ( &prime;).
