Abstract
An apparatus is proposed for releasably locking a bolt in the axial direction relative to a housing element surrounding it, in which the bolt has a circumferential groove tapering radially inward and a locking element inserted into this groove with a cross section adapted to that of the groove. The locking element protrudes radially beyond the cross section of the bolt and is in contact there on both sides with support surfaces, one of which is formed by the housing and the other of which is axially displacable under a compressive force load; at least one of these support surfaces is inclined, to provide a radially outwardly oriented reduction of the cross section formed between the support surfaces.
