Abstract
A plug-type connection for a tubular body comprising a tubular holding element (1) slit in crown-like manner to form tongues (2) to receive the tubular body (30), and an annular collet (20) to be inserted onto the holding element (1) to clamp the end region of the tubular body (30) to the holding element (1). The collet (20) is a single piece and U-shaped in longitudinal section and has an inner arm (21) which is slit in crown-like manner and an outer arm (22). A circumferential shoulder (8) is formed on the holding element (1) outside the central bore (3). A pin (26) on the end of the outer arm (22) of the collet (20) fits into a depression (9) in the shoulder (8) of the holding element (1). A spherically shaped projection (27) fits into spherically shaped recess (10) in the shoulder (8) of the holding element (1). The recess (10 ) is staggered by an angle of rotation with respect to the depression (9). The spherically shaped projection (27) is located on the end of the pin (26).
