In the case of a plug-in coupling for connecting a pipe end section (1) to an end section (2) of a hose or the like, a coupling sleeve (3) is provided whose one end section (15) is connected by vulcanisation to the end section (2) of the hose and on which elastic locking catches (7), which extend in the axial direction, are integrally formed. The locking catches can be latched by means of a hook end (9) behind a retaining rib (4) which is circumferential on the pipe end section (1) and tapers conically towards the end face (5) of the pipe end section (1). A seal is provided between the pipe end section (1) and the coupling sleeve (3). In order to simplify the production and assembly of such a plug-in coupling, it is ensured that the locking catches (7) are integrally formed on the one end of the coupling sleeve (3), that the end section (15) of the coupling sleeve (3) facing away from this end is embedded in the end section (2) of the hose by means of the vulcanisation and that the one opening edge of the hose end section (2) expands to correspond to the conical taper of the retaining rib (4) and rests on the conical surface (10) of the retaining rib as a result of the prestressing exerted by the locking catches (7). <IMAGE>
