A connector, having a socket part and a plug part being insertable into a socket section of the socket part, wherein the plug part is provided with a retaining element for detachably retaining the plug part in the socket part, the retaining element having a retaining arm with at least one outwardly projecting engaging catch, a free end, and an end secured to the retaining element body and can be spring-elastically moved in the radial direction in relation to the plug part for blocking the engaging catch on a blocking surface or a blocking opening of the socket part and releasing it from same, and a locking device being provided for securing the blocking status of the plug part and socket part and for indicating an incorrect assembly thereof, the locking device cooperating with the retaining element, and being a radially insertable locking element that cooperates with the retaining element in the region of the retaining arm thereof.

A food reflux reducing two-piece nasogastric tube includes a first tube body and a second tube body. The first tube body has a first connector on one end, and a protrusion edge on an outer side of the first connector in adjacent to the first positioning portion. The first connector has a through hole having a seal portion in adjacent to the first positioning portion. The seal portion has a cross break. A convex portion is on an inner edge of the through hole between the seal portion and the first positioning portion. The second tube body has one end provided with a second connector and an insertion combination tube extending therefrom. Two elastic arms extend from an outer side of the second connector and comprise a hook portion respectively. Thus, the second tube body is efficiently connected with and removed from the first tube body.

A quick connect and disconnect system for a fluid coupling includes an axially extending fitting configured to be secured to a fluid conduit, a clip, and a quick connect and disconnect adaptor. The clip is coupled to the fitting and includes a base, a wing extending from the base, and a first lug extending from the first wing. The quick connect and disconnect adaptor includes a first release tab configured to resiliently deflect through an aperture of the adaptor. The adaptor is configured to transfer a compressive force to resiliently deflect the first lug to move the clip in an axial direction from an installed position to an uninstalled position.

A connection device for connecting a tubular connector provided with an annular collar to an item of equipment comprising a passage, the connection device comprising:—a connection end fitting connecting to the passage of the item of equipment, the connection end fitting being formed by a tubular body with a head mounted thereon, the head being provided with a through-opening and comprising an ellipsoidal annular groove;—a locking ring having at least two longitudinal flexible legs for insertion into the connection end fitting, each having an outer surface bearing at least one lug intended to engage in the annular groove in order to hold the locking ring secured to the connection end fitting. The two flexible legs can be deformed and closed on the tubular connector in order to abut their free ends against the collar when the male connector is inserted longitudinally into the locking ring.

Fretting wear in a pipe connector is avoided in advance. In a connector body (1), there is provided a gate member (29) having spring portions (33) that allow a pipe (P) to be inserted up to a regular depth while maintaining a contact state with the pipe (P). When a retainer (37) is pushed in with the pipe (P) being inserted to the connector body (1) up to the regular depth, locking legs (45) of the retainer (37) are locked to a bulge portion (6) of the pipe (P) and each locking leg (45) enters between the pipe (P) and the spring portion (33) and elastically displaces the spring portion (33) in a direction away from the pipe (P), thereby eliminating the contact state.

A connector is provided which has first and second connectors. The first connector includes a first connector including a first housing. The first housing includes a substantially cylindrical first mating portion formed on a front end thereof. The second connector includes a second housing configured to be mated with the first housing. The second housing includes a substantially cylindrical second mating portion formed on a front end thereof. The second mating portion configured to receive the first mating portion. The second mating portion further includes a separating space, a mating main body portion separated by the separating space, and a mating main body deformation restricting portion. The mating main body deformation restricting portion is configured to restrict the amount of deformation of the mating main body portion.

A quick connect and quick disconnect adaptor for a fluid coupling system is provided. The adaptor includes a first half having a center point, and a sidewall at least partially defining a plurality of bores. Each of the bores contains an aperture, and each of the bores terminates at the center point. The first half further includes a plurality of release tabs. Each release tab is configured to resiliently deflect through an aperture, and each release tab terminates at the center point. The adaptor further includes a second half, which is at least partially symmetric to the first half.

A holding element for a terminal connector, having at least one socket part and at least one plug part, wherein the plug part can be inserted or is inserted in a socket portion of the socket part. The holding element can be plugged or is plugged onto the plug part for detachably holding the plug part in the socket part. The holding element has a holding element body, holding arms having latching lugs that are directed inwards with respect to the holding element, holding arms having latching lugs that are directed outwards with respect to the holding element, and axially on both sides, has an uninterrupted, continuous edge on the end side. The holding arms each have a free end that is spring-elastically movable in the radial direction, and an end opposite thereof that is fixed to the holding element body.

A push-to-connect fitting is provided. The push-to-connect fitting includes a connector body, a sealing member, a grab ring, a cartridge, a retainer sleeve, a plurality of latches, and an interference portion. A method of mounting the retainer sleeve over a portion of the connector body is done simultaneously while pushing the plurality of latches located on the retainer sleeve to secure the retainer sleeve to the connector body.
