1. A one-part male bayonet connector with which at least one first component and a second component are releasably connectable with each other in a non-destructive manner via an opening in each of the at least one first component and the second component, the bayonet connector having a T-like form in a lateral view, wherein
the bayonet connector comprises a head, a central shaft extending from there and two radially opposite thread webs extending from the central shaft and being configured rigidly, wherein each of the two thread webs comprises a fastening means of the bayonet connector facing the head, so that by means of a form-fit bayonet connection, the at least one first component and the second component are fastenable between a bottom side of the head and the fastening means of the thread webs such that the bottom side of the head is configured to be arranged at a side of the at least one first component facing away from the second component and the fastening means are configured to be arranged in recesses of the second component or at a side of the second component facing away from the at least one first component, wherein
the two thread webs define a right-handed thread or a left-handed thread and include a pitch angle a with respect to a plane that is normal to a central longitudinal axis of the central shaft in the range of 30°<α<50°, wherein
the fastening means of each thread web is a locking web or a semi-spherical like projection and
the two thread webs include a continuously decreasing radial extension in the direction facing away from the head of the shaft, so that the radial extension of the thread webs at the end of the shaft which faces away from the head has reduced to zero and, in an axial direction opposite of the head, the bayonet connector ends in a finder tip which is formed pointed, rounded, blunt or angular.
