On the one hand, they stiffen the housing and give in particular the sliding sole is very stable for use. To the others they form guides for the return springs as well for the pivoting movement of the seal carrier. they are non-destructible no longer.
  • the one with the peg-shaped projections of the upper housing part interacting counter-elements of the sliding sole are appropriate as stubby cylindrical elements with mushroom head educated. Several of these elements are over the surface the sliding sole is distributed. According to a preferred Execution of the invention are additional on the sliding sole Locking projections formed on the connector of the upper housing part and on the wall surfaces of the upper housing part are fixable. They snap into corresponding counter elements on. This gives the sliding sole in these areas additional stability.
