ABSTRACT:
Device for the removable fastening of a plate-shaped component onto a base with a T-groove open in the direction of the component. The invention consists of a pot-shaped receiving element, a head-bolt, a spring element arranged in the receiving-element and a cross bar arranged at the free end of the shaft of the head-bolt. The cross-bar is insertable in the T-groove and movable against the force of the spring element in the direction of the T-groove floor and engageable behind the shoulders of the T-groove by turning through 90.degree.. In accordance with the invention, the cross-bar has at least one stop interacting with one edge of the aperture of the T-groove in front of the head-bolt shaft end bearing the cross-bar. This stop prevents the continued turning of the head bolt after attainment of the locked position. The pot-shaped receiving element and the cross-bar are fitted with interacting means of guidance in such a way that the cross-bar can be moved axially from its locked position into its unlocked position, under guidance, by a turning movement of 90.degree..
