    The invention relates to a plug-in coupling for a pipe, in particular a water pipe, with a pipe end receiving, tubular coupling piece, with a sealing ring between Kuppiungsstück and pipe end and with an axially displaceable against the coupling piece supported guard ring, a radially projecting Mitnehmeranschlag for the front page forms the pipe end and covering the coupling piece mounted on the sealing ring during insertion of the pipe end into the coupling piece with respect to the end face of the pipe end
    There are pipe connections are known in which the pipe to be connected is pushed onto a connection nipple, which is enclosed by a sleeve, so that the pipe end must be inserted for pushing on the nipple in the annular gap between the nipple and the connection nipple tensile strength connected sleeve. The tightness of the connection connection is ensured by a sealing ring held in an annular groove of the connection nipple, over which the pipe end has to be pushed. There is a risk that the plugged onto the nipple pipe end the sealing ring with the front side damaged, especially when using metal pipes. In order to avert this risk of damage, it is known (EP 1 219 883 A2) to provide an axially displaceable guard ring on the connecting nipple, which covers the sealing ring and has a radially outwardly projecting driver lug on the rear end in the insertion direction, so that when sliding the pipe end Slide the end face of the pipe end along the guard ring over the sealing ring on the connecting nipple until the front end of the pipe end abuts the catch stop. The guard ring is therefore taken from the pipe end and subsequently pulled off axially by the sealing ring with the effect that the sealing ring the annular gap between the nipple and the deferred

    Seals pipe end. The disadvantage, however, is that the necessary safety to take the guard ring through the pipe end is missing when the driver lug is deflected by the end face of the pipe end against the nipple and therefore the pipe end slides over the guard ring.
    The risk of injury to the seal also occurs in plug-in couplings, in which the pipe end is inserted into a coupling sleeve which receives a sealing ring. The invention is therefore the object of a plug-in coupling with a sealing ring preferably between an outer coupling sleeve and an inserted tube in such a way that when the pipe end in the plug-in coupling a risk of damage to the ring seal can be excluded.
    Starting from a plug-in coupling of the type described, the invention solves the problem set by the fact that the protective ring has a front end of the pipe end inside and outside comprehensive, in cross-section U-shaped Mitnehmeranschlag.
    Due to the design of the Mitnehmeranschlags with a U-shaped cross-section ensures that the pipe end is remote from the Mitnehmeranschlag on the coupling piece facing away from the outside or inside, so that the so-called suspended in the pipe end Mitnehmeranschlag can not be deflected from the pipe end against the coupling piece and safely displaced by the pipe end in the axial direction to expose the gasket for abutment with the pipe end. This is especially true for an embodiment in which the tubular coupling piece is designed as a pipe sleeve enclosing the coupling sleeve with an inner sealing ring, because in this case because of the lower deformation resistance during expansion of the guard ring in the Mitnehmeranschlags a greater risk of deflecting the Mitnehmeranschlags radially outward is given, if this deflection is not counteracted by the proposed two-sided embracing the pipe end from inside and outside. ^ 0-09-2012 3 3 10 2012/50372

    Since the end face of the pipe end is encompassed by the guard ring on both sides, it is advantageously possible to pre-store the guard ring the sealing ring in the insertion direction, so that the sealing ring is no longer biased by the guard ring. The lack of support of the sealing ring upstream protection ring through the sealing ring plays for the safe entrainment of the guard ring by the inserted pipe end no role, because yes, due to the two-sided enclosure of the front end, the entrainment of the guard ring is secured.
    In order to secure the plug connection between the coupling sleeve and the pipe end, it is customary to axially support a sealing ring in the insertion direction of the pipe end in the coupling sleeve which forms radially projecting, inclined in the insertion retention claws These retaining claws tilt on the outer surface of the pipe end and prevent a withdrawal of the pipe end from the coupling sleeve. With an axial pipe load in the extraction direction, the retaining claws are acted upon with a torque counter to their direction of inclination with the effect that the retaining claws are pressed firmly against the pipe end. However, a prerequisite is that the retaining claws create a resilient bias to the pipe end when inserting the pipe end into the coupling sleeve. In order to reduce the resulting insertion resistance, the guard ring can cover at least the locking ring before inserting the pipe end into the coupling sleeve. But it is also possible to cover both the locking ring and the sealing ring with the guard ring. In both cases, the covered with the guard ring end face of the pipe end can slide over both the retaining claws of the locking ring and on the sealing ring.
    In the drawing, the subject invention is shown, for example. Show it

    Fig. 2 is a corresponding to Fig. 1 representation of the plug-in coupling according to the invention, but with inserted pipe end and Figs. 3 and 4 a Figs. 1 and 2 corresponding representation of an embodiment of a plug-in coupling according to the invention.
    According to the embodiment according to FIGS. 1 and 2, the plug-in coupling comprises a tubular coupling piece 2 receiving the pipe end 1 of a pipe to be connected, which in the selected exemplary embodiment is designed as a coupling sleeve 3 enclosing the pipe end 1 and inserted with an inner, into a receiving groove 4 Sealing ring 5 is provided, which connects the inserted into the coupling sleeve 3 pipe end 1 liquid-tight with the coupling sleeve 3, as shown in FIG. The usually inserted up to a frontal stop in the coupling sleeve 3 pipe end 1 is held with the aid of a relative to the coupling sleeve 3 axially supported locking ring 6, which extends in the plug-in direction inclined, supported on the pipe wall retaining claws 7 extending the pipe from the coupling sleeve. 3 prevented. The sharp-edged retaining claws 7 dig into namely in the surface of the pipe end 1 at a pipe load in the extraction, with an increasing pull the retaining claws 7 increasingly subjected to a bending moment against the claw inclination, resulting in an increasing wedging between the locking ring 6 and the pipe end. 1 leads.
    Since in particular on construction sites can not be expected that the pipe ends 1 are processed according to the front side to be pushed over the sealing ring 5 away in the coupling sleeve 3, without damaging the sealing ring 5, the sealing ring 5 in the coupling sleeve 3 against the inserted pipe end 1 covered by a guard ring 8. This guard ring 8 can cover the sealing ring 5 before inserting the pipe end 1 into the coupling sleeve 3. It is more advantageous, however, if the guard ring 8 is upstream of the sealing ring 5 in the insertion direction of the pipe end 1, because then the sealing ring 5 is not held under a bias by the guard ring 8 prior to insertion of the pipe end 1. The guard ring 8 must after the

    Recording the end face of the pipe end 1 are taken from the pipe end 1.
    For this purpose, the guard ring 8 is provided with a radially inwardly projecting driver stop 9 for the end face of the pipe end 1. The Mitnehmeranschlag 9 in this case has a the end face of the pipe end 1 inside and outside comprehensive, U-shaped cross section, so that when importing the pipe end 1 in the coupling sleeve 3 of the end face of the pipe end 1 on the coupling sleeve 3 facing away from the inside encompassing web 10 of the Mitnehmeranschlags 9, a sliding of the guard ring 8 effectively prevented from the end face of the pipe end 1 and ensures that the guard ring 8 is withdrawn from the sealing ring 5 and the sealing ring 5, the annular gap between the coupling sleeve 3 and the pipe end 1 directly seals, as shown in FIG ,
    The embodiment of a plug-in coupling according to the invention according to FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 essentially only in that the protective ring 8 engages over the locking ring 6, and not only the locking ring 6, but also the sealing ring 5 for Insertion of the pipe end 1 in the coupling sleeve 3 covering, which facilitates the handling of the plug-in coupling when inserting the pipe end 1 in the coupling sleeve 3.
    The guard ring 8 can be supported within the coupling sleeve 3 under a resilient bias on the inner wall of the coupling sleeve 3 and are therefore fixed purely non-positively in the axial direction, as indicated in FIG. 1. However, if a locking provided in a locking groove 11 as shown in FIG. 3, the axial position of the guard ring 8 relative to the coupling sleeve 3 can be structurally determined.
    The invention is of course not limited to the illustrated embodiments. Thus, the coupling body 2 could also be formed as a support sleeve, on which the pipe end is pushed. In this case, there is a kinematic reversal of the functions between the cooperating structural parts. Π 0-09-2012
