Embodiment Construction

[0024] Connecting accessories marked with 1 throughout are used to fix or fasten or join circumferentially ribbed elongated bodies, i.e. objects having alternating annular protrusions and recesses on their outer surface, as shown for example in the examples Out of the corrugated hose 2.

[0025] The connection attachment 1 has a clamping sleeve 3 into which the elongated body, ie the corrugated hose 2 in the exemplary embodiment, can be inserted axially and secured by a clamping projection which will be described further on.

[0026] In this case, at least one clamping ring 4 is used as the clamping projection, which is placed or fixed axially in the clamping sleeve 3 and which, in its seated position, is elastically expandable in the radial direction to such an extent , so that its internal cross-section or internal diameter, that is, its internal clear width corresponds to the maximum external cross-section of the elongated body or the corrugated hose 2, so that the corrugat...

Abstract

A connecting filling (1) used for fixing peripherally ribbed longitudinal bodies such as corrugated hoses (2), comprising a retaining bushing (3) into which the longitudinal body or corrugated hose (2) can be inserted in an axial direction and anchored by means of at least one locking, retaining, projecting element which, when insertion occurs, is radially offset in an outer direction and engages with a recess running along the periphery of the longitudinal body or corrugated hose (2), for instance a corrugation trough (2a). A retaining ring (4) which is fixed in an axial direction inside the retaining bushing (3) is used as a retaining projecting element. The ring can be expanded in an elastic manner in a radial direction until the inner diameter thereof is at least as large as the largest outer diameter of the longitudinal body or an undulation of the corrugated hose (2). The retaining ring (4) can be offset when the corrugated hose (2) is inserted and can engage with a recess or a corrugation trough (2a). The periphery of a plastic or metal retaining ring (4) is interrupted by a slit (5) which widens when the ring is expanded. An oblique or funnel-shaped surface (4a) enables the ring to be automatically expanded when the longitudinal body to be anchored or corrugated hose (2) is pressed against said surface in an axial direction.

Description

technical field [0001] The invention relates to a connection accessory for circumferentially ribbed elongated bodies such as pipes, hoses or cables, in particular for corrugated hoses, which has a clamping sleeve along which the elongated body or corrugated hose can be It is inserted axially into the sleeve and can be secured by at least one retaining projection which recedes radially outward during insertion and then engages with a recess extending along its circumference, in particular a valley. Background technique [0002] A connection accessory of this type is already known and proven effective from DE 39 03 353 and EP 0 381 979 B1. Elastically deformable tongues are now provided on the sleeve, each of which has a protrusion extending into the inner cross-section of the sleeve, which recedes when the elongated body or the corrugated hose is inserted, and then aligns with a circumferential Extended dimples or a trough mesh. As a result, only locally effective fixation ...
