Connection fitting with arrangement having two interconnected components

A connection fitting for connecting two components, comprising:

• a housing having a housing front side;
• a slide, which is longitudinally movable in the housing between a rear and a front slide end position, the front slide end of said slide being formed as a bushing which can be spread apart and which in the front slide end position protrudes beyond the housing front side;
• a bolt, which is arranged longitudinally movably in the slide and which, at one, front bolt end thereof, has a widened spreading head for spreading the bushing apart and which, at the other, rear bolt end thereof, has an undercut facing toward the spreading head;
• and
• a control element, which is mounted in the housing configured to be rotatable about an axis of rotation extending obliquely with respect to the bolt axis and which is rotatable in an installation direction of rotation from an initial position into an end position, the control element having a guide slot, the distance of which from the axis of rotation increases as viewed in the installation direction of rotation, having a radially inwardly facing tightening contour, the distance of which from the axis of rotation increases as viewed in the installation direction of rotation, and having a radially outwardly facing blocking contour, which extends over a circular segment about the axis of rotation;
• wherein, when the control element is rotated in the installation direction of rotation out of the initial position, in a first portion of the rotation, the control element pushes the slide, by means of a stud guided in the guide slot, into the front slide end position, and, in a second portion of the rotation, the slide is locked in the front slide end position by the blocking contour and the bolt is pulled radially inward by the tightening contour engaging behind the undercut, until, at the latest in the end position, the bushing has been spread apart by the spreading head.
