ABSTRACT:
A hose and pipe coupling is provided having a coupling head and a nozzle which can be inserted into the coupling head, and which is lockable therewith by a locking element. The locking element includes a spring-elastic ring having a slit and onto which are formed two oppositely-directed, arcuate spring arms which surround and embrace the coupling head. The coupling head has a slot-like circumferential opening and an internal annular groove for the partial reception of the spring-elastic ring and the nozzle at its coupling side is also provided with an annular groove for at least at partially receiving the spring-elastic ring in the inserted position of the nozzle. The coupling further includes a protective cap displaceably arranged on the coupling head and over the elastic ring after the nozzle and the coupling head are coupled together. The elastic ring includes a gripping knob formed at the outermost end of each of the spring arms thereof, and the protective cap is provided with radially-outwardly-protruding internal chambers for receiving the knobs. The protective cap also has formed therein an internal annular groove on an end portion thereof distal to the nozzle which is engageable with an annular shoulder provided in the coupling head.
